PDF to PNG or JPG: choose a clear image
Choose the pixels you need, then the format that keeps them useful.

For a text document, this gives you a useful first preview. Inspect small lettering before deciding whether you need more pixels.
Choose JPG for a photo-heavy scan when file size matters. The preview’s byte count tells you what that decision costs.
Format and resolution solve different problems
Resolution determines how many pixels describe the page. Format determines how those pixels are stored.
| Your page | Starting choice | What to inspect |
|---|---|---|
| Text, tables or line drawings | PNG, 150 ppi | Small text and thin lines. Increase resolution if their edges need more pixels. |
| A scan containing photographs | JPG, 150 ppi, 90% quality | Faces, gradients and lettering. Compare file size with PNG using Preview. |
| A page intended for print | PNG, 300 ppi | Whether its dimensions meet the printer’s requirement at the intended physical size. |
| A small document thumbnail | JPG, 72 ppi | Its appearance at the size you will actually display it. |
A worked example you can reproduce
The tool’s sample includes a US Letter page measuring 612 × 792 PDF points. At 72 points per inch, that is 8.5 × 11 inches.
Multiply those inches by the chosen resolution. These are calculated dimensions, not a speed or quality benchmark.
| Resolution | Image dimensions | Pixels |
|---|---|---|
| 72 ppi | 612 × 792 | 484,704 |
| 150 ppi | 1,275 × 1,650 | 2,103,750 |
| 300 ppi | 2,550 × 3,300 | 8,415,000 |
Open Try a sample, preview page 1, and switch resolutions to check these dimensions yourself. The landscape page swaps the two sides.
Why a sharper setting can still look blurry
More output pixels cannot recreate detail missing from a scan. They simply give the existing picture a larger grid.
- Vector text can be drawn again at a higher resolution, making edges clearer.
- A low-resolution scan contains a fixed amount of detail, even when it sits inside a PDF.
- JPG compression can add marks around text edges. Increasing quality reduces that new damage, but cannot undo damage already present.
PNG is lossless for the rendered image. Converting a PDF to PNG still replaces scalable text and shapes with fixed pixels.
Check pixels before printing
A 2,550-pixel image printed 8.5 inches wide supplies 300 pixels per inch. Print it 17 inches wide and that becomes 150.
The tool sets pixel dimensions, not a printer’s page-size setting or the image’s density metadata. Check the physical size in your print dialogue.
Export pages or extract photographs?
Exporting a page captures its visible layout, including text and images. Extracting an embedded photograph is a different task.
Use page export when you need a slide, receipt or document preview. If you need a photograph’s original bytes, use a dedicated embedded-image extractor.
Keep large documents manageable
Choose a small page range first. A single 300 ppi Letter canvas needs 33,660,000 bytes for its four-channel pixels, before other processing.
That is calculated raw canvas storage. Compressed downloads may be much smaller, and total browser memory can be higher.
- Preview a representative page and choose the lowest resolution that meets your task.
- Export a range rather than hundreds of pages at once.
- If the tool refuses a large page, reduce resolution. It will not silently shrink the output.
For private documents, browser-side conversion avoids uploading the file. The tradeoff is that your own device supplies the memory.
