Upload not responding or stuck?
Check the image format and size — we recommend keeping each file under 20MB. Oversized images can be compressed first before re-uploading.

Once you're happy with the result, click download to save it directly. Batch results can be packed into a single zip file for download.
Multi-Device Support
Works on both desktop and mobile, with slightly different controls
Core functionality is exactly the same — it's just that screen size differs, so some interaction details are adapted accordingly.
Desktop Browser
- 1Drag and drop or click to select filesDrag your image anywhere onto the page, or click "Select Files" to choose from a folder — you can select multiple files at once.
- 2Use your mouse for precise adjustmentsDragging a crop box or painting over a mosaic area is more precise with a mouse; some tools also support fine-tuning with arrow keys.
- 3Download directly when doneClick the download button and your browser will save the file to its default downloads folder.
Mobile Browser
- 1Tap the upload area to take a photo or pick from your camera rollTapping it brings up the option to choose from your photos or take a new one — either works.
- 2Zoom in first for precise draggingFor features like cropping and annotation, pinch to zoom in first, then drag the handles with your finger — touch targets have been optimized for mobile.
- 3Downloaded results are saved to your photos or downloads folderThe exact save location depends on your mobile browser's settings, but you'll usually find it in your photo library or a "Downloads" folder.

How to Use Smart Cutout(Using “Remove Background” as an example)
Swapping an ID photo's background color or creating a white-background ecommerce photo takes just 4 steps: upload, wait, change background, download.
- 1
Upload a portrait or product photo
Click the upload area or drag your image directly into the page. JPG, PNG, and WebP are supported, up to 20MB per image.
- 2
Wait for automatic subject detection
The first use may take a bit longer to download the processing component, which is then cached by your browser — subsequent uses usually only take a few seconds.
- 3
Choose a new background
Switch to a solid white, blue, or red background, a transparent background, or upload your own image to use as the new background.
- 4
Download the result
Once you're happy with the result, click download. To process the next image, simply upload it again.
Cutout result not quite right?Try using a source photo where the subject and background are clearly distinguishable with good contrast — fine details like hair strands will look more natural.

How to Convert and Compress Images(Using “Compress Image” as an example)
Solve “won't open” and “too big to upload” — the compression tool supports both a custom quality mode and a “target size” mode.
- 1
Upload the images you want to compress
Supports uploading multiple images at once, so you can process a whole batch instead of doing it one by one.
- 2
Choose a compression method
Drag the quality slider to set your own compression level, or switch to “target size” mode and enter your desired file size (e.g. 200KB).
- 3
Check the before-and-after comparison
Preview the resulting quality and file size change in real time, then export once you're satisfied.
- 4
Batch download
Download a single image directly, or pack multiple images into one zip file for download.
Not sure what compression level to pick?Just use “target size” mode — enter the upper limit your system requires, and the tool will automatically find the right balance of quality and file size, saving you time versus trial and error.

How to Resize and Frame Your Image(Using “Crop” as an example)
For avatar cropping, ID photo ratios, or trimming extra content, the crop box supports free dragging and common preset ratios.
- 1
Upload an image to bring up the crop box
The page will automatically display a draggable crop box overlaid on your image.
- 2
Choose a crop ratio
Freely drag to adjust the ratio, or select a common preset like 1:1, 4:3, or ID photo proportions.
- 3
Drag the handles to fine-tune
Both desktop and mobile support dragging the crop box's corner handles, with enlarged touch targets for easier precision on touchscreens.
- 4
Confirm and export
Once the preview looks right, export it. If you need a specific final size, follow up with the “Resize” tool.
Struggling to drag the crop box precisely?Maximize your browser window or pinch-zoom in on the image to make the corner handles easier to grab and drag accurately.

How to Use Creative Editing Tools(Using “Add Watermark” as an example)
For copyright protection and preventing image theft, watermarks can use text or an image asset, and can even tile across the entire image.
- 1
Upload the images you want to watermark
Supports batch upload so you can apply the same watermark to multiple images at once.
- 2
Choose a watermark type
Type in text to use as a watermark, or upload an image or logo to use as the watermark asset.
- 3
Adjust position, opacity, and angle
Place a single watermark at a fixed point, or tile it across the entire image to make it harder to crop out or steal.
- 4
Apply and export
Once you're happy with the effect, export it — batch images will all get the same watermark settings applied.
Want to protect a whole batch of images at once?A tiled watermark is harder to crop out than a single corner mark, making it better suited for anti-theft purposes.

How to Use Privacy & Utility Tools(Using “Mosaic / Blur” as an example)
Cover up phone numbers, addresses, and other sensitive details before sharing a screenshot — a few strokes and you're done.
- 1
Upload an image containing sensitive information
For example, a screenshot with a phone number, address, or house number.
- 2
Manually select the area to redact
Use your mouse or finger to paint over or box-select text like phone numbers or addresses — you can select multiple areas.
- 3
Choose a redaction effect
Mosaic block or Gaussian blur — the intensity of either effect can be adjusted.
- 4
Export the redacted image
The original image stays untouched; check the newly generated image carefully before sharing it.
About redaction safety:Redaction is an irreversible operation — under normal circumstances, the original covered content can't be recovered from the processed image, so you can share it with confidence.

Tips & Tricks
These situations are all completely normal
Here are a few of the most commonly asked details about the process — knowing them ahead of time can save you some confusion.
Processing taking longer than expected?
Features like background removal need to download a processing component the first time, which is then cached by your browser for much faster use afterward; large images or older devices will also take longer.
Not happy with the result and want to adjust it?
Most tools let you change settings and reprocess directly without re-uploading the image, so you can compare before and after at any time.
Can I choose the export format myself?
After processing, you can usually export as JPG, PNG, WebP, or another common format — the exact options depend on the specific tool page.
Do I have to process images one at a time?
Tools like compression, format conversion, and resizing all support batch mode — select multiple images at once, process them, and download the results as a package.
Could the processing leak my images?
No — everything runs locally in your browser. Images are never uploaded to any server, and everything is cleared as soon as you close the page.
FAQ
Common Questions About How to Use the Tools
How many images can I upload at once?
Most tools support batch upload, and the maximum number varies slightly by tool, with a hint shown on the page. We recommend keeping each image under 20MB for faster processing.
Does the image download automatically once it's processed?
No — you'll need to manually click the download button to save the result. Batch-processed images can be packed into a zip file for download.
What if my uploaded image's format isn't supported?
If the current tool doesn't support your image format, first use the “Convert Format” tool to turn it into JPG or PNG, then proceed with your original task.
Can I cancel or switch images halfway through processing?
Yes — most tools let you re-select an image or adjust settings and reprocess at any time, without needing to refresh the page and start over.
What's different about using this on mobile versus desktop?
Core functionality is the same; on mobile, the settings panel collapses into a bottom action bar. For precision tasks like cropping or annotating, we recommend zooming in first, or switching to a tablet or computer for finer control.
I forgot how to do something — can I come back to this page anytime for reference?
Yes — this page stays available, so you can come back and check the steps for any category whenever you need.
