Frequently asked questions

Why do websites ask for a PDF under 1 MB?

Many government and recruitment websites limit each attachment to 1 MB.

Will my document stay readable?

PDFmoji first tries without touching the text. If that is not enough, it turns the pages into images and picks the sharpest version under the limit. If 1 MB is truly impossible, it tells you and gives you the smallest readable file.

Is my file sent anywhere?

No. Compression happens in your browser: the file never leaves your device.

Is it really free?

Yes. Merging, splitting, compressing, converting, signing and filling are free and unlimited. With a free account you can also edit the text of 3 PDFs a month in their original font and make 10 Assistant requests. The 7-day pass (€4.99) or PDFmoji Pro (€7.99 a month, no commitment) removes these limits.
