Images to PDF
Combine JPG, PNG, or WebP images into a single PDF. Reorder pages before building. Everything runs in your browser.
How to use
- Drop one or more JPG, PNG, or WebP images. Drop additional batches to append them.
- Reorder with the up/down arrows, or remove an image with ×.
- Pick a page size. Auto sizes each page to the image it contains — good for mixed content. A4 or Letter gives every page the same size.
- Optionally set margins (mm) and orientation.
- Click Build PDF, then Download.
What does it do?
This tool assembles your images into a single PDF, one image per page. JPG images are embedded as-is without re-encoding, so photo quality is preserved exactly. PNG and WebP are embedded as PNG. You can set a fixed page size (A4 or US Letter) or use Auto mode, which makes each page the exact dimensions of its image — useful for combining scans, phone photos, and screenshots that have different aspect ratios.
Example
Realistic scenario:
Input: receipt-jan.jpg (1200x1800), receipt-feb.jpg (2048x1536 landscape),
receipt-mar.png (800x1200)
Settings: Page size = Auto, Margin = 5 mm
Output: receipts.pdf — 3 pages, each sized to its source image,
5 mm white border around each page. Why is my images-to-PDF output the wrong size or orientation?
Most surprise output comes from the page size and orientation settings not matching the images. The fixes are straightforward once you know what each option does.
- Landscape photo on a portrait page. With
Page size = A4andOrientation = Portrait, a wide image gets shrunk to fit the narrow page. Switch toOrientation = Autoso each page picks orientation from its image, or usePage size = Auto. - Tiny image on a huge page. A 400×400 screenshot on
an A4 page leaves a lot of white space. Use
Page size = Autoto match the page to the image. - HEIC from an iPhone didn't load.
image/heicis not supported by browsers' built-in image decoders. Convert to JPG in the Photos app (or AirDrop with "Automatic" disabled) before adding. - WebP looks slightly larger than the original file. WebP images are re-encoded to PNG during embedding (WebP isn't embeddable in PDFs directly), and PNG is lossless — so small highly-compressed WebPs can grow. Convert to JPG first if output size matters.
- Images are in the wrong order. Files are added in the
order they arrive from the drop event, not alphabetically. Rename
files with a numeric prefix (
01-cover.jpg,02-intro.jpg) before dropping, or reorder manually with the ↑ / ↓ buttons.
Is my data private?
Yes. We don't save the images you add to the PDF, and we don't keep the finished file you download either. Nothing is stored, logged, or retained — everything is discarded the moment you close or refresh the tab. There's no record on our side of what you converted. You're welcome to verify in your browser's developer tools.
Frequently asked questions
What image formats can I combine into a PDF?
JPG, PNG, and WebP are supported. JPGs are embedded directly without re-encoding, so no quality is lost. PNG and WebP are embedded as PNG. HEIC and AVIF are not supported — convert them to JPG or PNG first using the image resizer or your system converter.
Why did my output PDF come out larger than the sum of my images?
PDFs add a small amount of container overhead — cross-reference tables, page objects, fonts — so a PDF of small images is never smaller than the image bytes. For photos the overhead is negligible. For tiny line-art PNGs it can be a noticeable percentage.
Can I mix portrait and landscape images in the same PDF?
Yes. Use Page size = Auto and each page will be sized to fit its image exactly, so mixed orientations work without cropping or letterboxing. If you pick A4 or Letter with Orientation = Auto, each page picks portrait or landscape based on that image.
Will the tool reorder my images automatically, for example by filename?
No. Images appear in the order you added them. Use the up and down arrows next to each thumbnail to reorder. Dropping files in batches appends them to the end of the current list rather than re-sorting.
Is there a limit on how many images I can combine?
There is no hard limit, but browsers hold the entire PDF in memory. A few hundred phone photos is fine on a typical laptop. Several thousand high-resolution images may crash the tab — split them into multiple PDFs and merge the results with the PDF merger.
Do you save the images or the PDF I build here?
No. We don't save the images you add, and we don't keep the PDF you download either. Everything is discarded as soon as you close or refresh the tab — no logs, no record on our side of what you converted. Feel free to peek at your browser's developer tools if you want extra confidence.
