Frequently asked questions
Which DPI should I choose?
72 DPI for screens and chat sharing, 150 DPI for general use, 300 DPI when the image will be printed.
Can I convert only certain pages?
Yes. Type a range like 1-5,8 and only those pages are exported as images.
Why is my output a ZIP file?
Each PDF page becomes a separate JPG, so multi-page exports arrive bundled in one ZIP for a single download.
Will text stay sharp after conversion?
Text becomes pixels, so sharpness depends on DPI — 150 or 300 keeps body text crisp. If you need selectable text, keep the PDF.
Does converting compress my images?
JPG is a compressed format by nature; use the quality slider to balance size and fidelity.
Is my PDF uploaded for conversion?
No. Pages are rendered to images locally in your browser — the file never leaves your device.
