Question 1

How can I fit my scan under 50KB while keeping it readable?

Accepted Answer

Our compressor automatically adjusts scaling and removes redundant streams. For scanned files, we also recommend trying the Grayscale option to strip color data, which saves substantial space while keeping text readable.

Question 2

What should I do if my compressed PDF is still slightly over 50KB?

Accepted Answer

If your file is slightly over, you can crop any unnecessary border margins or adjust the quality settings. For PDFs, enabling both Grayscale and Metadata removal strips hidden bytes to help you squeeze under the limit.

Question 3

Will compressing to 50KB make my PDF blurry?

Accepted Answer

At 50KB there's some quality tradeoff, but text and faces stay recognizable - check the live preview before downloading.

Question 4

Is this PDF compressor free and does it require signup?

Accepted Answer

Yes, completely free, no signup, no daily limit, and no watermarks added to your files.

Question 5

Is my PDF uploaded to a server?

Accepted Answer

No - everything happens locally in your browser via client-side processing, so your personal files are never uploaded or shared.
