Frequently Asked Questions
Will compressing affect document clarity?
No. Text vectors, tables, and typography stay 100% crisp. The engine selectively optimizes oversized images and removes unreferenced binary data.
Is client-side compression safe for tax and bank forms?
Completely safe. Because files are never uploaded over the internet to remote servers, your sensitive financial statements remain 100% private.
Can I compress a PDF to under 100KB?
Yes. Use the target size chips (100KB, 200KB) to automatically downsample images to fit strict job application portal limits.
Is there any file size limit?
No artificial server upload caps. You can compress heavy PDFs directly on your device without upload wait times.
