Frequently asked questions
- How can I compress a PDF to less than 100KB?
- Type or keep 100 under Fit under a size and click Fit under 100 KB. The tool tries each image setting in turn and, for a scan, renders the pages as pictures at falling resolutions until the file fits. A long text document may not get under 100 KB; then remove pages you do not need or split the file.
- Are my certificates and personal files uploaded to a server?
- No. All compression runs locally on your device in the browser. Zero bytes are uploaded to our server or any third party.
- Will my text remain readable at 100KB?
- It depends on the document. If the image settings are enough, the text is untouched. If the pages have to be flattened, the tool can go as low as 50 dpi, where small print blurs. The note names the setting used, so open the result and check it; if it is not readable, untick flattening and remove pages instead.
