Frequently asked questions
- Will I still be able to select or search text after compressing?
- Often no. To shrink the file, the compressor may rasterise each page into an image — once that happens, text in the compressed PDF can't be selected, searched, or copied. If selectable text matters more than file size, use a higher quality level or skip compression entirely.
- How small will my file get?
- It depends on what's inside. Image-heavy PDFs often shrink by 80–95% at the Low setting. PDFs that are mostly text shrink less, because there's less to compress.
- Can I set an exact target size in KB?
- Not here. Real-world PDFs vary too much for an exact target to be honest — we'd rather show you the actual result than promise a number we can't reliably hit. Pick Low for the smallest file, then check the result.
- Is my file uploaded anywhere?
- No. Compression runs entirely in your browser with WebAssembly. The PDF never leaves your device.
- Is there a file size limit?
- Not from us. The practical limit is your device's available memory. Modern laptops handle PDFs of several hundred megabytes.
