How to convert PDF to JPG
- Add your PDF.
- Choose the sharpness. 150 DPI is a good default.
- Leave Pages empty for every page, or type the ones you need.
- Set a KB limit per image if your form has one.
- Check the preview, then save the JPG or the ZIP.
When you need a JPG instead of a PDF
Some portals only accept images: a mark sheet, a certificate or a signature page that you have as a PDF. Converting the page gives you a JPG the form takes. If the form also sets exact pixels, use a photo tool with that form’s preset afterwards.
Going the other way? JPG to PDF puts images into one PDF.
Questions
Is my PDF uploaded?
No. ReadyFile draws the pages in your browser, on your own phone or computer. Your document never leaves your device.
Which DPI should I choose?
150 DPI suits most forms and screens. Choose 200 or 300 for small print or printing, and 100 for the smallest files. Higher DPI means more pixels and bigger files.
My form wants a JPG under 200 KB. Can this do it?
Yes. Set the limit to 200 KB. Each image is saved at the best quality that fits, and made smaller only if it can't fit without turning blocky. The result tells you if that happened.
How do I get just one page?
Type its number in Pages, for example 2. One page saves as a single JPG; several save together as a ZIP.
How do I open the ZIP?
On Windows and Mac, double-click it. On Android and iPhone, the Files app opens ZIPs.
My PDF has a password. Can I still convert it?
Yes. Enter the password when asked. It's only used to open the file on your device.
