Compress a PDF
Shrink a PDF so it fits an email or upload limit — pick a quality level and BrowsePDF re-encodes the pages right on your device. Free, no login, and your file is never uploaded.
- Choose your own quality level
- Re-encoded on your device, never uploaded
- Free, no account needed
Compress in three steps
- 1
Drop in your PDF
Add the oversized file — the scanned report or image-heavy deck that won't send.
- 2
Pick a quality level
Choose how hard to compress, trading a little image quality for a smaller file.
- 3
Download the smaller PDF
Save the shrunk copy, ready to attach or upload.
Smaller file, same document
You choose the trade-off
Compression means giving up a little image quality for a lot less file size, and how much is up to you. Pick a lighter setting to keep pages crisp, or a heavier one to squeeze under a strict email or upload limit. BrowsePDF downsamples and re-encodes the pages so the file comes out smaller without changing what it says.
- Choose your own quality level
- Downsamples and re-encodes images
- Great for scans and image-heavy PDFs
- Get under an email or upload cap
Best on scans and image-heavy files
The weight in most bloated PDFs is pictures — phone-camera scans, full-page screenshots, high-res photos in a portfolio. Those shrink dramatically. A text-only PDF, like an exported invoice, is already small, so there's little to trim; compression helps most exactly where the file is heaviest.
Compressed on your device, not ours
Plenty of compressors ask you to upload your file first — so your bank statement or client deck takes a round trip through someone's server just to lose a few megabytes. BrowsePDF handles it all in your browser instead. The pages are re-encoded on your device, nothing is uploaded, and the only file that moves is the smaller one you save.

Compressing a PDF: FAQ
Is my PDF uploaded to compress it?
No. The downsampling and re-encoding run on your machine, so the original never gets sent anywhere. You download the lighter copy, and nothing else moves.
Will compression lower the quality?
It can — compression is lossy, trading some image detail for a smaller size. You choose the quality level, so you decide how much detail to give up to hit the size you need.
Which PDFs shrink the most?
Image-heavy files and scans see the biggest drop, since photos and scanned pages carry most of the weight. A text-only PDF is already compact, so there's little left to remove.
Is it free, and is there a watermark?
Yes, it's free with no login, and nothing is stamped on the compressed file. You just get a lighter version of your original.
Is there a file size limit?
Because it runs in your browser, the practical limit is your device's memory rather than a server cap. Very large scans work best on a computer with a bit of headroom.
About compressing PDFs
Almost everyone hits the same wall eventually: an attachment that won't send, an upload form that rejects the file, a portal with a hard megabyte cap. Usually the culprit is images — a document scanned on a phone, a slide deck full of screenshots, a photo-heavy report. The content is fine; the file is just heavier than the pipe it needs to fit through.
Compressing trims that weight by downsampling and re-encoding the images inside the PDF, and BrowsePDF lets you pick how aggressive to be so you keep the quality you actually need. It all happens in your browser, so the statement or contract you're shrinking never gets uploaded just to save a few megabytes. Since compression is lossy, keep your original if you might need full resolution later — but for getting a file out the door, a smaller copy is usually all anyone wants.
