- Rough capacity of 10 MB: ~682 text-only pages, ~171 grayscale scanned page(s), about 47 full-colour photo page(s).
- Runs in your browser: files are never uploaded. Free, unlimited, no watermark.

Who needs a PDF under 10 MB?
Email attachments (corporate mail servers often cap at 10 MB), messaging apps and cloud forms.
Tips to fit 10 MB with the best quality
- Large presentations and photo reports fit without visible quality loss.
- Remember attachments grow ~33% when emailed (base64), so 10 MB on disk can be ~13 MB in an email.
- For Gmail's 25 MB limit see our email guide.
How we hit 10 MB exactly
Most compressors apply one fixed setting and hope the result is small enough. We search for it: first we remove waste (duplicate objects, metadata, thumbnails), then re-encode the images at progressively lower resolution and quality, checking the size after each try and keeping the highest quality that is still under 10 MB. Only if images alone can't get there do we flatten pages, and we say so on screen.
Frequently asked questions
Why does a 9 MB PDF bounce from a 10 MB email limit?
Email encodes attachments as base64, adding about a third to their size. Compress to about 7 MB to send safely through a 10 MB limit.
Are my PDFs uploaded to a server?
No. Compression runs entirely inside your browser using JavaScript and WebAssembly-grade libraries. Your file never leaves your device, so confidential documents stay private. You can even disconnect from the internet after the page loads and it keeps working.
Will my text stay selectable and searchable?
Yes in the normal modes: we keep text, fonts, links, bookmarks and form fields and only re-encode the images inside the PDF. Only if you ask for an exact size that cannot be reached that way do we flatten pages into images — and the tool tells you when that happens.
Is there a file size or daily limit?
No daily limits, no sign-up and no watermark. The only limit is your device's memory — most phones handle PDFs up to a few hundred MB and computers handle more.
