Images to PDF

Runs in browser PDF Conversion

Accepts JPG, PNG, WebP, GIF, BMP, TIFF and HEIC (where the browser can decode it). Order the images, pick a page size, margins, orientation and fit, and download a single PDF.

Privacy: Processed locally in your browser. Your file is not uploaded.

When should PNG, JPEG or WebP be used?

PNG is lossless with transparency, right for screenshots, diagrams and anything with sharp edges or text; JPEG is lossy and much smaller for photographs; WebP offers both modes at roughly 25–35% smaller sizes than the older formats and is supported by every current browser. Converting a page to an image fixes its appearance but loses the text layer, so the choice depends on whether the result must stay searchable.

The 16:9 photo is illustrative; Letter and 12 mm are from the example. Automatic orientation (the default) gives it a landscape page. The default page size, “Fit each page to its image”, adds no margin and crops or stretches nothing.

Frequently asked questions about Images to PDF

Which image formats are accepted?

JPG, PNG, WebP, GIF, BMP, TIFF and AVIF anywhere the browser can decode them; HEIC/HEIF on Safari. SVG is not supported because it is vector text, not pixels.

How are the pages ordered?

In the order of the list. Dropped files are sorted naturally (img-2 before img-10); use the arrows to change the order.

Can I get one page size for all images?

Yes — choose A4, Letter or another size, then "Fit inside the page" to keep each image whole, "Fill the page (crop)" to cover the area inside the margins and crop what overflows, or "Stretch to the page" to ignore proportions.

Is my PDF uploaded to a server?

No. The file is opened and processed by your browser with WebAssembly and JavaScript; nothing is sent to Mutqan Soft or anyone else. Close the tab and the file is gone. Downloading the result needs a free account — no subscription, no payment.

What are the size limits?

Up to 250 MB and 2,000 pages per operation on a desktop browser, 60 MB and 500 pages on a phone, because everything runs in your device’s memory. The tool tells you before it starts if a file is over the limit.

Technical notes

Every input is sniffed by its bytes, not its extension; JPEG and PNG pass through untouched, other formats go through the browser decoder. Pages are created by pdf-lib with the chosen size and the image drawn at the computed rectangle.
