Each row becomes one page of the PDF: drag a row or click the up/down arrows to reorder, or replace/delete a page.
Upload multiple images, drag to set the order, pick A4 or auto-fit page size, then click generate — all pages are merged into a single PDF entirely in your browser, great for putting together application materials, scanned documents and paperwork submissions, no sign-up and no waiting.
The PDF is assembled locally in your browser — your material photos never pass through any server
Drag to reorder or move pages up/down before generating, and replace or delete any single page
Choose A4 portrait/landscape for printing and submissions, or auto-fit sizing for on-screen viewing
No sign-up, no payment, no hidden usage limits
Common Use Cases
Anytime “only one file is accepted,” merging scattered images into a single PDF in order is the safest way to submit.
Exam registrations, onboarding paperwork, and visa applications often require you to combine the front and back of an ID, proof of education, photos and more into a single uploaded file. Arrange your material photos in the required order and merge them into one PDF with a single click — it's a far better fit for system requirements than uploading one by one or zipping them, and it's easier for reviewers to work through too.
No scanner for a contract, invoice, or paper notes? Snap a photo of each page with your phone, straighten and crop each one first, then merge them in page order into a single PDF — that gives you a “scanned copy” ready to email or send through an approval workflow, and it prints cleanly as a standard A4 portrait document too.
Merge a set of design work, product photos, or property listing images into one PDF to send to a client — they can download it once and flip through it in the order you intended, instead of it getting compressed or shuffled the way a pile of separate images does through chat apps. Choose auto-fit sizing so every page keeps the original image's proportions for the best presentation.
Page Settings
The default “A4 Portrait + Standard margin” fits most submission scenarios — adjust using the table below for special cases.
| Setting | Description | Best For |
|---|---|---|
| A4 Portrait | Standard A4 portrait page — images are scaled proportionally and centered, never stretched or distorted | IDs, certificates, portrait-oriented photos, or materials that need printing or formal submission |
| A4 Landscape | Standard A4 landscape page, with the same rules as portrait otherwise | Wide tables, landscape-orientation screenshots, or files made up mostly of landscape photos |
| Auto-fit to image size | Each page's proportions exactly match its own image, and pages can differ in size | Portfolios or catalogs meant for on-screen viewing that don't need a uniform paper size |
| Margin | None / Narrow / Standard — controls the blank space between the image and the page edge | For files meant to be printed, a standard margin is recommended to avoid content being cut off at the edge |
| Image quality | Controls the compression level of images written into the PDF — lower quality means a smaller file | When the PDF exceeds an upload size limit, lower this and regenerate |
Note: each generation produces exactly one PDF, and all pages share the same page size, margin, and quality settings. Changing any setting or the page order will invalidate the previously generated result — just click “Generate PDF” again to output it with the new settings.
How to Use
No software to install — everything happens right in the browser.
Click to select or drag your images into the page — select multiple at once. Supports JPG, PNG, WebP and GIF, up to 20MB each, up to 50 at a time.
Each row in the file list becomes one page of the PDF — drag a row directly to reorder it, or use the up/down buttons for fine adjustments, and replace or delete any single page.
Choose A4 portrait, A4 landscape, or auto-fit to image size, then adjust the margin and image quality as needed.
Click generate PDF — all your images are merged in your browser, in the current order, into a single PDF file, ready to download and save.
Technical Notes
Each image is first re-encoded on your device using the browser's built-in Canvas capability, then written page by page into the PDF document structure and assembled entirely in memory before being saved directly to your device. The whole process doesn't rely on any online conversion service — your material photos and the resulting PDF never leave your device, and it even works offline.
This tool's “batch” behavior works differently from tools like compression or format conversion, which process multiple images and produce multiple independent results. Image to PDF is fundamentally about merging: you select multiple images, each occupying one page in list order, and the output is always a single PDF. If you need several independent PDFs (for example, one per ID document), split your images into separate batches and generate each one separately.
FAQ
It's done entirely in your current device's browser: each image is first re-encoded locally, then assembled in browser memory into a single, complete PDF following the PDF document format — no image or generated PDF is ever uploaded to a server.
Yes. The Image to PDF tool lets you drag to reorder each image before generating, and you can also delete or replace any single page. Once you're happy with it, export — the result matches the preview exactly.
No. This tool's batch feature means you can select multiple images to merge at once, but the output is always a single PDF file, with each image occupying one page in list order. If you need several independent PDFs, split your images into separate batches and generate each one on its own.
For submitting application materials, paperwork, or anything that needs printing, A4 is recommended (portrait for vertical materials, landscape for wide tables) — it's the most universal paper size, and images are scaled proportionally and centered on the page. If you're just packaging images into one file for on-screen viewing, choose auto-fit sizing so each page matches the image's own proportions with no extra whitespace.
The PDF's size is mainly determined by the images themselves — try lowering the image quality slider and regenerating. If it's still too large, compress each image first with the Compress Image tool, or shrink the resolution with the Resize Image tool, then come back here to merge into a PDF.
This tool directly supports JPG, PNG, WebP, and GIF (using the first frame). For HEIC, please batch-convert to JPG first using this site's Convert Format tool, then come back here to merge into a PDF — both steps happen locally in your browser and are never uploaded.
