- Rough capacity of 1 MB: ~68 text-only pages, ~17 grayscale scanned page(s), about 5 full-colour photo page(s).

Tips to fit 1 MB with the best quality
- Presentations exported to PDF commonly drop from 10–30 MB to under 1 MB.
- Text, links and bookmarks are preserved — recruiters can still search your CV.
- We treat 1 MB as 1,000,000 bytes, so the file passes strict and lenient checks alike.
How we hit 1 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 1 MB. Only if images alone can't get there do we flatten pages, and we say so on screen.
Frequently asked questions
How do I make a PDF under 1 MB for a job application?
Choose “Exact size”, set 1 MB, drop in your CV. We compress the images inside it and keep the text selectable, which matters because many hiring systems read the text automatically.
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.
