- Pages are drawn by Mozilla's open-source pdf.js, loaded once (about 2 MB) and run on your device.

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many PDF files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting PDF to BMP reduce quality?
Pages are drawn fresh at the resolution you pick, so text and vector shapes stay sharp. Use 300 dpi for print-quality images.
What about documents with several pages?
Each page becomes its own image, named with its page number, and you can download them all as a ZIP.
