Compress PDF online
Compress a PDF Online Free — Shrink File Size in Your Browser
Compress PDF files online for free. Reduce file size for email and uploads entirely in your browser — no account required.
Need to shrink a large PDF before emailing it or uploading it to a form? Our free compress tool runs in your browser so the file does not have to leave your device for everyday compression.
Open the tool, pick your PDF, choose a size target (for example 2 MB for many job portals), and download the smaller file. Smart mode keeps selectable text; maximum mode flattens pages to images.
How to do it
- Open Compress PDF.
- Choose your file.
- Pick smart or maximum, then a quality level or a 2 MB target.
- Check the preview and download.
FAQ
Is compressing PDF online free?
Yes — core compression on techyworks is free and ad-supported.
Do you upload my file?
Compression runs in the browser for this tool; the file is not uploaded to our servers for the standard flow.
Why did the size barely change?
Text-only or already-compressed PDFs have little left to shrink. Try maximum mode only if you accept losing selectable text.
