Frequently Asked Questions

Everything you need to know about compress pdf

How much can I reduce a PDF file size?

Typically 40–90% depending on content. Image-heavy PDFs compress the most. Text-only PDFs compress less but still significantly.

Will compression reduce image quality?

Medium compression is nearly imperceptible to the human eye. High compression reduces image resolution — choose based on your use case.

Is my file secure?

Yes. All files are encrypted in transit (TLS 1.3) and automatically deleted from our servers after 60 minutes.

Is there a file size limit?

No hard limits. Files up to 500MB work reliably. For very large files use our batch processor.

How do I compress a PDF to under 1MB?

Upload your PDF and choose "high compression". Most PDFs compress to under 1MB. For very large files, use medium compression to balance size vs. quality.

Can I compress a PDF on my phone?

Yes. EditDocs AI works on any device with a browser — iPhone, Android, tablet, or desktop. No app download needed.

Does compressing a PDF damage the text?

No. Text in PDFs is stored as vectors, not images. Compression only affects embedded images. Text always stays perfectly sharp.

What makes EditDocs AI compression different?

EditDocs AI uses AI to intelligently target only the elements that can be compressed without perceptible quality loss. You also get batch compression, free API access, and your files are deleted in 60 minutes — not stored on servers.
