Frequently asked questions

Will compression reduce the quality of my PDF?+

PhantomEtch uses intelligent compression that optimizes embedded images and removes redundant data without affecting visual quality. Text, vectors, and layout remain pixel-perfect. You choose the compression level that fits your needs.

How much can I reduce the file size?+

Results vary depending on the PDF content. Image-heavy documents typically see 50-80% size reduction. Text-heavy PDFs with few images may see 10-30% reduction. PhantomEtch shows you the before and after sizes so you can decide.

Is there a file size limit?+

Since everything runs in your browser, the limit depends on your device's memory. Most users can comfortably compress PDFs up to 100MB. For very large files, ensure you have enough free RAM.

Is my data safe during compression?+

Completely. PhantomEtch processes everything locally in your browser. Your files are never uploaded to any server. We literally cannot see your documents — your data never leaves your device.
