About this tool

Images to PDF combines any number of JPG, PNG, or WebP images into a single PDF document — one image per page by default. Drop your images, drag the thumbnails to reorder them, pick a page size (A4, US Letter, A3, or fit-to-image), an orientation, and a margin in pixels, then click Convert. The result is a clean, watermark-free PDF that you can email, archive, or print. Common use cases include turning a stack of phone photos into a single shareable document, building a one-PDF portfolio from chart screenshots, packaging scanned receipts for an expense report, or creating an offline-friendly comic or photo album. Everything runs in your browser via pdf-lib — your images never leave the device, which matters for personal photos, ID scans, medical documents, and confidential design comps. PNG transparency is preserved.

Why use it

  • Browser-Only Privacy: Images and the resulting PDF never leave your device — pdf-lib runs entirely locally.

  • Drag-Reorder Thumbnails: Visual drag-and-drop on each image preview makes setting page order intuitive.

  • Multiple Page Sizes: A4, US Letter, A3, or 'fit to image' — choose what makes sense for your audience.

  • Lossless JPG and PNG Embed: Images are embedded as native JPG or PNG objects — no recompression, full quality preserved.

  • Free, No Watermark, No Signup: Output is clean and unbranded with no daily limit, account, or paid tier.

  • PNG Transparency: Transparent PNGs keep their alpha channel intact when converted to PDF pages.

How to use

  1. Drop one or more JPG, PNG, or WebP images onto the upload area — multiple files supported.
  2. Drag thumbnails left/right to set the order pages will appear in the PDF.
  3. Click × on any thumbnail to remove that image before converting.
  4. Pick a page size: Fit to Image (custom per-page), A4, US Letter, or A3.
  5. Choose orientation (Auto / Portrait / Landscape) and a margin in pixels around each image.
  6. Click 'Convert to PDF' and download — the output is a single watermark-free PDF.

When it helps

  • When you have a stack of phone photos and want to email them as a single PDF rather than ten attachments.
  • When packaging scanned receipts for an expense report submission.
  • When turning a series of chart screenshots into a one-PDF presentation handout.
  • When archiving photos of a whiteboard from a meeting into one shareable document.
  • When creating a portfolio PDF from a folder of design comps or product shots.
  • When converting screenshots from a phone or tablet into a single offline-friendly PDF for review.

12 PNG receipt scans, fit to image, 16 pt margin

Expected result

Expected result

portfolio.pdf — 20-page A3 landscape PDF, design comps centred

Tips

  • Sort image filenames numerically (01.jpg, 02.jpg) before dropping to make the initial order match your intent.
  • Use 'Fit to image' when image sizes vary — each page comes out matching its image's aspect ratio.
  • For mixed portrait/landscape photos, leave Orientation on Auto so each page gets the right direction.
  • JPGs are typically smaller than PNGs — for photos use JPG sources to keep the output PDF lean.
  • After conversion, run PDF Compress if file size matters — high-resolution images can balloon the PDF.

Frequently Asked Questions

What image formats are supported?
JPG, JPEG, PNG, and WebP. Use JPG for photos (smaller files), PNG when you need transparency, and WebP for the best size/quality ratio.
Are images recompressed?
No — pdf-lib embeds JPGs and PNGs as native objects without recompressing, preserving full quality. Output PDF size is essentially the sum of source image sizes plus a small wrapper.
Will image quality be preserved?
Yes — embedding is lossless. The PDF page contains the exact same image bytes as your source file.
Does it work with HEIC photos from iPhone?
Not directly — HEIC is not supported in browsers. Convert HEIC to JPG first using your phone's share/export option, or any HEIC-to-JPG converter, then drop the JPGs here.
Can I have multiple images per page?
No — each image becomes its own page. For multiple images per page, use a layout tool first to compose the images, then convert the resulting layout image to PDF here.
Maximum number of images?
Limited by browser memory — typically 50–100 images at full phone-photo resolution work comfortably. For very large batches, split into chunks and merge the resulting PDFs.
Is the order preserved?
Yes — the order in the thumbnail grid (after any drag-reorder) is the order pages appear in the output PDF.
Are my images uploaded?
No. pdf-lib runs entirely in your browser. Both the input images and the output PDF stay on your device.

Glossary

JPG/JPEG
A lossy photo format with high compression and no transparency — best for photographs in image-to-PDF workflows.
PNG
A lossless image format with optional alpha-channel transparency — best for screenshots, charts, and logos with transparent areas.
WebP
A modern Google image format offering both lossless and lossy compression at better ratios than JPG/PNG.
Fit to Image
A page-sizing mode where each output page matches its image's aspect ratio with the chosen margin around it.
Aspect Ratio
The proportional relationship between image width and height — 1:1 square, 16:9 widescreen, 4:5 portrait phone.
Embed
Adding an image to a PDF as a native PDF image object — pdf-lib uses embedJpg or embedPng without recompressing.
