Frequently Asked Questions
How can I compress a PDF to under 200KB or 100KB for application portals?
Select the Extreme <200KB preset. Resumes and text documents exported from Word or Google Docs easily drop below 100 KB while keeping text sharp. If your file is a phone scan or photo PDF, our tool automatically converts the pages into lightweight images so you can pass strict portal limits.
Does compressing a PDF make the text blurry?
No. On Low and Recommended modes, text fonts and vector lines are not touched at all, so letters stay sharp at any zoom level. Only heavy embedded photos are resized to normal screen and print resolution.
Is it safe to compress private documents like bank statements or IDs?
Yes. Most PDF websites upload your files to their cloud servers. Our tool runs locally inside your web browser—your documents never leave your computer or phone.
Why did my PDF size barely change?
If a PDF only contains plain text or images that are already compressed, there is very little extra weight left to remove. Rather than ruining the quality of your file, we keep your original intact.
Does this work on iPhone and Android phones?
Yes. You can compress files directly in mobile Safari or Chrome without installing any apps.
