About this tool
PDF Compress reduces file size so documents fit email, job portals, and upload limits. It works especially well on scan-heavy PDFs.
Adjust quality to balance readability and size. Processing stays in your browser — nothing is uploaded to a server.
Tip — Start with a medium quality setting, then check size before going lower.
FAQ
Will text become unreadable?
Text-heavy PDFs are usually fine; image pages may look softer at lower quality. Check the preview first.
When should I compress?
When attachments are too large for email or when a site has an upload size limit.
How much smaller will it get?
It depends on the file. Image-heavy PDFs shrink more; text-heavy ones may shrink less.
Are files uploaded to a server?
No. Every tool runs entirely in your browser. Files and text you enter are never sent to our servers.
