Why OTL

Why use Image to PDF Converter

Works with any format

PNG, JPG, WEBP, GIF, BMP, and anything else your browser can open — mix them freely in one batch.

Perfect for screenshots

Non-photo images are embedded losslessly, so sharp text and clean UI edges stay exactly as crisp as the source.

Mixed-format batches

Combine JPGs, PNGs, and graphics from different sources into one consistent PDF, no pre-conversion needed.

Never stretched or cropped

Each image keeps its exact aspect ratio — nothing is squeezed to fit a page or cut off at the edges.

Nothing uploaded

Every image is decoded and packaged into a PDF locally in your browser tab.

Free, no watermark

No account, no trial limit, and nothing stamped into your converted document.

Deep dive

About Image to PDF Converter

Not every "image to PDF" job starts with a camera photo. Just as often it's a folder of screenshots for a bug report, a handful of PNGs saved from a website, or a mix of graphics and scans from different sources that all need to land in one PDF before you can send or file them.

This tool handles any of that: PNG, JPG, WEBP, GIF, BMP, and most other formats your browser can open, mixed freely in the same batch. Screenshots and other non-photographic images are embedded losslessly, so sharp text and clean UI edges stay exactly as crisp as the source — nothing gets run through JPEG-style compression unless it already was one. Camera photos are handled just as well, with the same automatic orientation correction so nothing comes out sideways.

You get the same two layout choices either way. "Original image size" sizes each PDF page to match the image exactly, pixel for pixel — usually the better pick for screenshots and graphics, where you want the output as close to the source as possible. "Fit to A4 page" instead centers each image on a standard page, switching to landscape automatically when needed — the better pick if you plan to print the result.

Because everything — reading, correcting, and assembling the final PDF — happens locally in your browser, this works just as well for a batch of internal screenshots or design mockups as it does for anything more sensitive, since nothing is ever uploaded anywhere.

Pro tips

Pro tips

  • "Original image size" is usually the better choice for screenshots and graphics — it keeps every pixel exact instead of scaling to a print page.
  • Batches of many high-resolution screenshots can produce a larger PDF than you'd expect — that's the lossless encoding working as intended, not a bug.
  • Mixing JPGs and PNGs in the same batch is fine — each image is processed and encoded independently.
  • Reorder before converting — page order always matches the order shown in the grid.
  • Converting camera photos instead? This tool handles EXIF orientation automatically too, so either tool works — pick whichever name matches what you're converting.

Privacy & security

A batch of screenshots or scans can add up to a surprising amount of personal detail once it's all in one file, so local processing matters here too.

Every image in your batch is processed on your device — nothing is uploaded, even briefly.

No account or signup required, regardless of how many images or formats you combine.

The moment you close the tab, there's no trace of your files left on any server.

Handles a folder of work screenshots the same way it handles personal photos.

FAQ

Frequently asked questions

Is my image uploaded to a server?

No. Every image is decoded and packaged into a PDF entirely in your browser — nothing is ever uploaded.

Can I mix different image formats in the same PDF?

Yes. Add a mix of PNG, JPG, WEBP, and other formats — each is processed and placed independently, so mixing formats is never a problem.

Will screenshots stay sharp, or will they get compressed?

Screenshots and other non-JPEG images are embedded losslessly, so no compression is applied — text and UI elements stay perfectly crisp.

Does it work for photos too, or only screenshots and graphics?

Both. It handles camera photos — with automatic orientation correction — just as well as screenshots and graphics. It's a general-purpose image-to-PDF converter.

What image formats are supported?

PNG, JPG, WEBP, GIF, BMP, and most other formats your browser can display.

Is there a limit on how many images I can add?

No hard limit — very large batches just take a little longer since everything processes on your device.

Stuck?

Troubleshooting

My screenshot text looks slightly different

It shouldn't — non-JPEG images are embedded losslessly with no compression applied. If something looks off, compare against the original screenshot file itself.

The PDF file is larger than I expected

Lossless PNG encoding (used for screenshots and graphics) produces larger files than JPEG compression. That trade-off keeps text and sharp edges perfectly crisp.

One of my images won't convert

The file may be corrupted or in a format your browser can't decode. Try opening it in an image viewer first to confirm it's valid, or re-save it as a JPG or PNG.

The images are in the wrong order

Use the up/down arrows on each thumbnail before converting — the PDF follows the exact order shown in the grid.
