Can I compress a PDF on my phone?

Yes! Docpressor works in mobile browsers on both iOS and Android. Upload your PDF directly from your phone's file manager and download the compressed version.

Do I need Adobe Acrobat to compress PDFs?

No. Docpressor provides the same compression functionality directly in your browser, without requiring any software installation or subscription.

What's the best MB target for email?

For most email providers, 5MB is a safe target. Gmail allows up to 25MB, but corporate servers often limit to 5-10MB. We recommend compressing to 5MB for universal compatibility.

How much can I reduce a PDF's size?

It depends on the content. Scanned documents (mostly images) can typically be reduced by 70-90%. Text-heavy PDFs may see 20-50% reduction. Docpressor always shows you the final size before you download.

Is there a way to compress multiple PDFs?

Yes! Docpressor's batch mode lets you compress up to 100 PDFs at once. All files are processed simultaneously and delivered as individual files.

How to Compress PDF — Everything You Need to Know

Compressing a PDF used to require expensive desktop software like Adobe Acrobat Pro. Today, you can reduce any PDF's file size directly in your browser, on any device, in under 15 seconds.

The key to effective PDF compression is choosing the right target size. Here's a quick guide: For HMRC/GOV.UK submissions, target 3.5MB. For court e-filings and email, target 5MB. For HR portals and applications, target 10MB. For general sharing, 5MB works for most situations.

Scanned documents benefit the most from compression because they contain high-resolution images that can be optimized significantly. A 20MB scanned document can typically be reduced to 3-5MB while remaining perfectly readable.

For power users, Docpressor offers batch compression — upload up to 100 PDFs and compress them all to the same target in one operation. Combined with a PRO subscription ($12.99/month), you get unlimited processing with no per-file charges.
