Question 1

Why would I need 380KB instead of a smaller size?

Accepted Answer

Larger targets like 380KB preserve more detail - useful for Presentation Decks where high clarity, rich colors, and printing fidelity matter more than minimal file size.

Question 2

Can I compress high-resolution photography down to 380KB?

Accepted Answer

Yes, our tool can downsample large multi-megapixel files to 380KB easily, preserving excellent colors and edge contrast for professional presentation.

Question 3

Is 380KB a safe limit for large ebooks or portfolios?

Accepted Answer

Yes! 380KB allows for generous file bandwidth, meaning multi-page portfolios, slides, and manuals can maintain highly detailed diagrams and crisp typography.

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?
