Frequently Asked Questions

Is my PDF uploaded to a server?

No. FyleTools processes everything directly in your browser using WebAssembly. Your file never leaves your device.

What's the difference between Optimize and Compress?

Optimize PDF performs deeper cleanup — compressing images, removing metadata, and eliminating unnecessary objects. Compress PDF focuses primarily on image compression. For best results, try both.

Does optimization affect text quality?

No. Only embedded images are compressed. All text remains crisp, selectable, and searchable. Fonts and vector graphics are preserved.

How much space can I save?

Results depend on the PDF content. Files with large images typically see 50–80% size reduction. Text-heavy documents with few images may see smaller savings.

What is the difference between Compress and Optimize?

Compress focuses on reducing image quality inside PDFs. Optimize is broader — it also removes metadata, unused objects, and optimizes the internal structure.

Will optimization break any PDF features?

No. Text remains selectable, links stay clickable, and forms continue to work. Only redundant data and metadata are removed.

Does this work on my phone?

Yes. Upload a PDF from your phone and optimize it directly in your browser. Perfect for reducing file sizes before emailing.
