Frequently Asked Questions
- How does the target size work?
You give a size in MB. The tool re-encodes the images at several quality levels and returns the highest quality result that still fits under your target.
- What if the target is impossible?
Below some point the text, fonts and structure alone weigh more than your target. You get the smallest version the file allows, with its actual size shown, rather than an error.
- How many pages can one PDF have?
100 pages on the free plan, 500 on Premium, 2000 on Pro. Page count is checked before processing starts, so an oversized file fails immediately instead of halfway through.
- What happens to my file after processing?
It is uploaded over HTTPS, processed, and deleted 24 hours later by an automatic storage rule. Files are never used for anything other than your own conversion.
- What are the size limits?
Free: 100 MB per file and 5 files at a time, 8 conversions a day without an account and 20 when signed in. Premium: 500 MB and 20 files. Pro: 1 GB and 50 files.
