How to use this tool
- Drag your PNG images into the drop zone, or click it to browse.
- Reorder the list with the ↑/↓ buttons — each image becomes one page, in that order.
- Click "Convert Images to PDF" — the finished PDF downloads straight to your device.
Common mistakes to avoid
- Transparent areas in a PNG will show as white in the PDF — flatten onto a background first if that matters for your file.
- Very large batches of high-resolution images will use more of your device's memory — close other tabs if it feels slow.
Why convert PNG to PDF in the browser instead of uploading it?
Most free PNG-to-PDF converters upload your images to a server first. This tool uses pdf-lib to build the PDF using your device's own CPU and memory, so your images — often screenshots or design files with sensitive content — are never transmitted anywhere.
Frequently asked questions
- Does converting PNG to PDF keep transparency?
- No — PDF pages don't support transparent backgrounds, so any transparent areas in your PNG will render as white in the output.
- Can I combine multiple PNGs into one PDF?
- Yes — add as many PNGs as you need and reorder them with the ↑/↓ buttons; each image becomes its own page, in that order.
- Does this also work with JPG images?
- Yes — this tool accepts both PNG and JPG, so you can mix formats in the same PDF if you need to.
- What size will each PDF page be?
- Each page is sized to match its source image's exact pixel dimensions, so nothing gets cropped or stretched.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical free PNG-to-PDF sites |
|---|---|---|
| File ever leaves your device | No — 100% client-side | Yes — uploaded to process, then deleted per their retention policy |
| Daily conversion limits | None | Common on free tiers |
| Image count cap | None imposed by us (device-memory bound) | Often capped on free tiers |
| Account required | Never | Often, past a certain usage level |
