PDF · up to 100 MB per file
Turn a pile of images into one PDF, one image per page. There are two ways to lay out the pages, matching two needs. Matching each image (the page wraps the image exactly, no borders) suits scans and long screenshots for archiving — nothing extra to print. Fixed paper (A4, A3, A5, Letter, Legal) suits anything that will be printed or bound: images are scaled proportionally and centred, never cropped and never stretched (a shaved edge or a squashed face are the two most common reasons a print job comes back). Orientation can follow each image, so landscape photos get landscape pages — the least wasteful arrangement when printing. Everything happens on this machine.
Features
- Combine many images into one PDF, one per page, in the order you chose them
- Pages can match each image, or be fixed to A4, A3, A5, Letter or Legal
- Orientation follows each image (landscape images get landscape pages)
- Margins of 0, 10 or 20 mm
- Proportional scaling and centring: never cropped, never stretched
- Accepts JPEG and PNG only — PDF embeds just those two, and the tool will not silently re-encode
- Nothing is uploaded and no server is involved
How to use
- Drop several JPEG or PNG files in
- Choose the page size and orientation
- Choose a margin if you want one
- Download the PDF
FAQ
- Why can I not use WebP, GIF or HEIC?
- A PDF embeds images in only two ways: DCT (which is JPEG) and Flate (which is PNG); anything else has to be re-encoded first. This tool will not silently re-encode for you — that inflates the file or degrades it, and you would only find out on receiving a 300 MB PDF when you thought you were just "putting pictures in". Convert them to PNG or JPEG with the image converter first.
- Are the images recompressed?
- No. JPEG and PNG are embedded as they are, with no change to pixels or file size. The flip side: ten 4 MB phone photos produce roughly a 40 MB PDF. To make it smaller, run each through the image compressor and hit a target size first, then combine.
- What happens if I mix portrait and landscape images?
- With "match each image", every page fits its own picture, so the PDF contains both portrait and landscape pages — the view turns as you page through, which is expected, and printing follows each page. With fixed paper and orientation set to follow the images, landscape ones automatically get landscape pages, so you still get both. For uniform pages, fix the orientation instead: images are then scaled proportionally and centred inside the page.
- Are the images uploaded?
- No. Combining runs through pdf-lib in the browser's memory. The images never leave the machine, and it keeps working offline.

PDF Merge
DocumentsCombine several PDFs in the order you choose, or take only certain pages from each. Rename the result; contracts never leave your browser.
Image Converter
ImagesConvert between PNG, JPEG, WebP, AVIF, BMP and TIFF, with adjustable quality and size. JPEG output lays a background, so transparency never turns black.
Image Compressor
ImagesCompress an image to a target size (say under 200 KB): the tool binary-searches for the highest quality that fits. Quality steps and size limits too.
PDF Split
DocumentsExtract pages into one file, or split into a file per N pages. Output names carry the page range, so a file sent on still makes sense. Nothing is uploaded.
PDF Page Numbers
DocumentsStamp page numbers on every page: six positions, three formats, a start value and a size you choose, and an option to skip the cover.
