Frequently asked questions
What should I check for a 100 KB file?
At 100 KB, start with one cropped page. Fine print and detailed photos may become hard to read; keep the original and inspect the result at full size.
Will a 100 KB PDF keep selectable text?
A PDF already under the target stays unchanged. Larger files are converted to compressed page images, so text may no longer be selectable.
Is the requested file size guaranteed?
No. Some documents cannot fit without losing too much detail. The result shows the actual size and warns if the target was not reached. Keep the original and use a larger allowance if needed.
How are kilobytes measured?
These tools use 1 KB = 1024 bytes. Check the destination website: a limit measured in decimal kilobytes may be slightly smaller.
Is Compress PDF to 100 KB free?
Yes. You can use Compress PDF to 100 KB for free, without creating an account.
Are my files uploaded?
No. Compress PDF to 100 KB works inside your browser, so your files never leave your device.
Does it work on phones?
