Compress PDF Online

Why do PDFs get so big? Usually it's the pictures inside. Scans made at high resolution can easily push a file past 20 or 30 MB. Fonts add weight too. So do leftover bits of data from whatever program made the file. The result? An email that won't send, a form that won't upload, a chat app that rejects your attachment. Our free online tool was built to reduce PDF file size for email and any other place with strict limits — including those heavy scanned documents most other tools can't shrink below 10 MB.

Here's how we shrink PDF online without losing quality. We look at every image in your file and save it in a smarter format — dropping the resolution from print-quality down to screen-quality when that's all you need. Text stays sharp. Pictures stay clear. We also trim fonts down to only the letters your document actually uses, which can cut off several megabytes by itself. Then we squeeze the rest of the file in a way that doesn't lose a thing. You pick the level: Less Compression keeps images crisp. Recommended hits the sweet spot and usually gets files down to 100KB–500KB. Extreme is for when you absolutely need to compress PDF to 100kb or 200kb — like those strict government portals or job application forms.

Your files are safe. Every upload goes over a secure connection, and we delete the PDF from our servers within one hour — no copies, no backups, no peeking. Because the heavy lifting happens on our side, even big scanned files compress fast, even on an old laptop or a phone. Need to email a 50-page contract? Got a CV to upload with a 1 MB limit? Want to archive a year of receipts? Our online tool handles large scanned PDF documents in seconds and hands you back a smaller, email-ready file.
