Use Cases
No need to learn tool names first — see which situation matches you
ID photos, ecommerce product shots, redacting chat screenshots, converting application materials to PDF — most people who open an image processing site are thinking “I need to solve this problem,” not the name of a specific tool. This page organizes 8 real-world use cases with the corresponding approach and tool combination — find your scenario and jump straight to it.
ID Photos & Resume Materials
Applying for jobs, exams, or visas always seems to require a “white background ID photo,” a “blue background passport photo,” or a file “under 200KB” — but a quick photo on your phone never has the right size, background color, or file size, and a trip to the photo studio costs both time and money.
This is for you if
- A job site or resume system requires “white background, formal wear, 2 inch” but all you have is a phone photo
- An exam or visa application specifies a blue or red background ID photo
- You want to skip the trip to a photo studio and get it done at home in a few minutes
How to solve it
- 1Use “Crop” with an ID photo ratio to frame the portrait areaSupports common ratios like 1-inch, 2-inch, and visa photos, precisely capturing the head and shoulders.
- 2Use “Remove Background” to swap in the required background colorAutomatically detects the portrait outline and switches to a solid white, blue, or red background in one click.
- 3Use “Compress Image” to get under the required file sizeSet a target size directly (e.g. 200KB) — no trial and error needed.
Common ID Photo Size Reference
| Type | Size (mm) | Pixels (300dpi) | Common Use |
|---|---|---|---|
| 1-inch photo | 25 × 35 | 295 × 413 | Resumes, work IDs |
| 2-inch photo | 35 × 49 | 413 × 579 | Exam registration, some visas |
| Small 2-inch | 35 × 45 | 413 × 531 | Some professional exams |
| US visa photo | 51 × 51 (2×2 in) | 600 × 600 | US visa applications |
| Japan visa photo | 45 × 45 | 531 × 531 | Japan visa applications |
FAQ for this use case
What if different applications require different background colors (white/blue/red)?
After running your photo through the background removal tool once, you can swap the background to white, blue, red, or any other solid color as many times as you need — the same photo can be re-exported to meet different requirements without a reshoot.
Ecommerce & Product Photos
Launching new products means matching a platform's requirement for a pure white background and consistent dimensions — but each platform has different specs, and manually adjusting real product photos one by one is slow and error-prone, especially with a large batch of new items.
This is for you if
- You need to swap real product photos for the pure white background a platform requires
- Your main image and detail-page photos need to be standardized to the same size and ratio
- You need to process dozens of product photos at once, and adjusting each one individually is a waste of time
How to solve it
- 1Use “Remove Background” to batch-extract each productAutomatically detects the product outline and removes the cluttered background.
- 2Swap in a pure white or specific background colorMatches most ecommerce platforms' white-background requirement for main images.
- 3Use “Resize” to export a consistent platform-standard sizeBatch-export to a square or platform-specific ratio — main images and detail-page photos done in one pass.
- 4Use “Collage Maker” for multi-angle layoutsCombine multiple detail shots into a single comparison or presentation image.
Common Ecommerce Main Image Specs
FAQ for this use case
Ecommerce main images need a white background — can the cutout tool do that?
Yes. The tool first detects the product and removes the original background, then switches it to a solid white background in one click, matching most ecommerce platforms' main image requirements. It also supports uploading multiple product photos at once for batch processing.
Form & System Upload Limits
Uploading to a website or system keeps showing “image too large” or “format not supported” — form submissions and application systems' file size and format restrictions often stall the entire process.
This is for you if
- The form requires images under 200KB, but your phone's original photos are several MB each
- The system only accepts JPG/PNG, but your photo is in HEIC format
- You need to merge several material photos into a single PDF for submission
How to solve it
- 1Use “Convert Format” to turn HEIC and other formats into JPG/PNGConvert any format the system doesn't recognize first for the best compatibility.
- 2Use “Compress Image” to get under your target sizeJust enter the size limit and it'll automatically find the right balance of quality and file size.
- 3Use “Image to PDF” when you need to merge materialsMerge multiple images into a single file, in order, ready for submission.
Tip:Instead of repeatedly adjusting quality and re-uploading, just use “target size” mode — enter the upper limit the system requires (e.g. 200KB), and the tool will automatically match the right quality level in one pass.
FAQ for this use case
I already compressed the image, but the upload still says it's too big. What should I do?
We recommend using the compression tool's “target size” mode — enter the system's upper limit (e.g. 200KB) and the tool will automatically find the right balance between quality and file size, saving you the time of manually adjusting compression level over and over.
Privacy & Information Security Redaction
You want to share a screenshot or group photo, but the frame might contain a phone number, house number, or ID number — and the location data embedded in the photo itself can quietly reveal where you've been.
This is for you if
- You want to share a screenshot in a group chat or on social media but need to blur out some text first
- You're sharing a shipping label photo for a secondhand sale and need to cover the phone number and address
- You want to strip the location data from travel photos before sharing them
How to solve it
- 1Use “Mosaic / Blur” to paint over sensitive areasManually select text areas like phone numbers or addresses and redact them in one click.
- 2Use “EXIF Viewer / Remover” to strip location dataRemove capture time, device info, and GPS location from a photo.
About privacy:Like every other tool on this site, these two run entirely in your browser — images are never uploaded to any server, so you can download and share the result as soon as it's ready.
FAQ for this use case
After applying a mosaic or blur, can the original content still be recovered?
Mosaic and blur redaction performs an irreversible transformation on the pixels in the painted area to generate a new image — it's not a simple overlay layer. Under normal circumstances, the original content before processing can't be recovered.
Office Materials & Scanned Documents
Onboarding, expense reports, and applications often require submitting multi-page materials, but all you have are a few phone photos — crooked, with a shadow from the desk in the frame — which look unprofessional if sent as-is.
This is for you if
- You need to merge multiple photos, like both sides of an ID card or a diploma, into a single PDF
- A crooked document photo needs straightening, or the extra desk background needs cropping out
- The scanned file is too large and needs compressing before it can be uploaded
How to solve it
- 1Use “Rotate / Flip” to straighten the photoRotate to any angle to correct a skewed shot.
- 2Use “Crop” to trim the extra edgesCrop out the desk, fingers, or other irrelevant content, keeping only the document itself.
- 3Use “Image to PDF” to merge them in orderCombine multiple materials into a single PDF for easy, unified submission.
- 4Use “Compress Image” to control the final file sizeMeet email attachment or system upload size limits.
Common Applicable Materials
FAQ for this use case
After merging multiple images into a PDF, can I still change the page order?
Yes. The image-to-PDF tool lets you drag to reorder each image before generating the file, and you can delete or replace any individual page. The exported result will always match the preview.
Design & Content Creation Asset Prep
When writing an article or working on a design, you often need to quickly grab a color value, dress up a plain screenshot with rounded corners, or combine a few result images into a single comparison graphic.
This is for you if
- You want to know the HEX/RGB value of a color from a design mockup or reference image
- A plain app screenshot looks dull, and you want to add rounded corners, a border, and a shadow
- You need to combine several variations or before/after results into one comparison image
How to solve it
- 1Use the “Color Picker” to grab a value directly from an imageGet HEX, RGB, and HSL values to plug straight back into your design tool.
- 2Use “Rounded Corners / Border / Shadow” to dress up screenshotsAdd rounded corners and a drop shadow to an asset for a more polished presentation.
- 3Use “Collage Maker” to build a comparison imageArrange multiple assets in a row, column, or grid layout for presentation.
FAQ for this use case
Is the color picker's precision good enough for design work?
The color picker reads the actual pixel color data from the image directly, outputting HEX, RGB, and HSL values with precision matching the image's own resolution — plenty accurate for everyday design color-picking and matching screenshot colors.
Photography Enthusiasts & Photo Library Cleanup
iPhone photos default to HEIC format, which won't open on many platforms or when transferred to a Windows computer; a photo library full of mixed formats, orientations, and sizes is a headache to organize.
This is for you if
- HEIC photos sent via chat or uploaded to a website don't display, and the recipient can't open them
- You want to batch-convert a set of photos to JPG or WebP for easier archiving
- You have a lot of sideways or upside-down photos that need straightening in bulk
How to solve it
- 1Use “Convert Format” to batch-convert to JPG / WebPUpload a whole batch at once and convert them all to a universal format.
- 2Use “Rotate / Flip” to straighten them in bulkCorrect the orientation of sideways or upside-down photos all at once.
- 3Use “Compress Image” to save space in your library or cloud storageSignificantly reduce storage usage while keeping an acceptable level of quality.
Common Formats Supported for Conversion
FAQ for this use case
Will batch-converting HEIC or old photo formats reduce quality?
Format conversion preserves the original resolution and quality by default. If you also enable compression, you can choose your own quality level or target size, freely balancing sharpness against file size — nothing is forcibly downgraded.

Social Media & Content Creator Covers
Blog covers, video covers, and post covers on different platforms all use different aspect ratios, so uploading directly often crops out the important part — and a bland cover image also hurts your click-through rate.
This is for you if
How to solve it
Common Social Platform Cover Ratios
FAQ for this use case
Different platforms use different cover ratios — do I need to crop separately for each?
Yes, cover ratios usually differ between platforms, so it's best to crop once per platform using its specific ratio. The crop tool supports custom ratios, and once cropped, you can also batch-export common preset sizes with the resize tool.
