Three steps, no upload
Everything below happens locally. Close the tab and nothing is left behind.
Add your PDF
Drag a file in or pick one from disk. You can queue several PDFs and convert them together.
Choose resolution
150 DPI is right for screens and 300 DPI for print. Turn on merge when you want one long image instead of separate pages.
Download pages
Each page becomes its own PNG, or one merged image per file. Grab them one by one or download everything as a single ZIP.
Which resolution should you pick?
Output size below is for an A4 page. US Letter is slightly smaller.
| DPI | A4 output | Best for |
|---|---|---|
| 96 | 794 × 1123 px | Quick previews and thumbnails |
| 150 | 1240 × 1754 px | Web pages, slide decks, email |
| 300 | 2480 × 3508 px | Printing, archiving, OCR |
| 600 | 4960 × 7016 px | Fine print, catalogs, large formats |
Questions
Are my files uploaded to a server?
No. The PDF is parsed and rendered by JavaScript running in your browser. Your file stays on your device, which also means there is no upload time and no copy left on someone else's disk.
Can I merge all pages into one image?
Yes. Turn on “Merge pages into one image” and every page of a file is stitched into a single PNG. Choose vertical or horizontal stacking, and keep “Trim whitespace” on to remove the empty margins — including the blank band at the bottom of A4 pages — before stitching.
Is it really free?
Yes. No account, no watermark, no page limit. The tool is supported by the desktop version, the Doc2Img desktop app, which adds high-fidelity DOCX output and batch automation.
What is the best DPI for a PDF to PNG conversion?
Use 150 DPI for anything that will be viewed on a screen, 300 DPI for printing, and 600 DPI when the page contains small text or fine line work. Higher DPI means larger files and more memory use.
Can I convert a password-protected PDF?
Not yet. Remove the password in your PDF reader first, then convert the unlocked file.
Does every page become a separate image?
By default yes. A 12-page PDF produces 12 PNG files, named document-01.png through document-12.png. Use “Download all” to get them in one ZIP, or turn on merge to get one image per source file.
