Compress PDF
Shrink PDFs to fit email limits and upload forms, without sending them anywhere.
Pages are redrawn as images, so text will no longer be selectable.
Is your website slow too?
Heavy files slow down websites as well.
Oversized PDFs and images are a top reason business websites load slowly. I optimise whole sites for speed and Core Web Vitals.
Why are some PDFs so big?
- Scans: every page is a large photo, often at 300 dpi or more.
- Phone photos dropped into a document at full camera resolution.
- Embedded fonts and duplicate images from design software.
Frequently asked questions
Is my PDF uploaded to compress it?
No. Compression happens inside your browser, so the file never leaves your device. Large files may take a little longer on older phones.
Which level should I choose?
"Recommended" works best for scanned documents and PDFs full of photos, often making them 50 to 90% smaller while staying sharp on screen. "Light" keeps text selectable but only saves a little. "Maximum" gives the smallest file for email limits.
Why can I not select text after compressing?
"Recommended" and "Maximum" redraw each page as a compressed image, which is what makes the big savings possible. If you need selectable or searchable text, use "Light".
What is the size limit for email?
Most email services accept attachments up to 20 to 25 MB. Many upload forms (job sites, government portals) ask for under 2 to 5 MB, which "Recommended" usually achieves.
