Compress PDF to 1MB
Upload your PDF and it compresses toward 1MB automatically — same pages, same layout, just smaller. Everything happens in your browser; your file is never uploaded.

Sizes are estimates from your first page. The result stays a real PDF — same pages, same layout, only smaller.
We adjust quality to land as close as possible. If your target cannot be reached without ruining quality, we will tell you honestly.
The 1MB sweet spot for email
Most email providers accept attachments up to 25MB, but corporate mail servers, university inboxes and older clients often cap attachments far lower — and a 1MB file sails through every one of them. Compressing your PDF to 1MB is the safe universal choice when you're emailing a CV, a signed contract or a scanned application: small enough to never bounce, large enough that text stays crisp.
What to expect
Upload your PDF and the tool targets roughly 1MB automatically. Text-based PDFs (reports, invoices, forms) usually reach 1MB with no visible change at all. Scanned pages are re-rendered as optimized images, so fine print in a low-quality scan may soften slightly — the page dimensions, layout, links and page count never change.
When 1MB is the right target
Choose 1MB when the recipient's limit is unknown: job portals that say "keep it small", professors' inboxes, client email threads, or anything you'll forward more than once. If your file is already under 1MB the tool tells you honestly that no compression is needed instead of pointlessly reprocessing it.
Tips for the smallest clean file
Remove unneeded pages first with Split PDF, and strip hidden metadata with Remove Metadata — both shrink the starting size so the 1MB target is reached with less quality trade-off. Everything runs in your browser, so even confidential documents are safe to compress here.
