PDF to PNG
Every page of the PDF is rendered and saved as a separate PNG, packaged in one ZIP. PNG is lossless, which is why it suits text, line art, and screenshots.

Pick a resolution, then convert.
PNG is lossless, so there is no quality setting. If the files come out larger than you want, drop to 1× or export the pages as JPG instead.
Conversion complete
Your PNGs are ready
Every page is a separate PNG inside one ZIP. The file stays available in this tab until you convert another PDF or leave the page.
Counted with the browser's own PerformanceObserver from the moment this page finished loading, analytics included. It reports what it observes rather than proving a negative: resource timing does not cover WebSocket connections, work a browser extension does on your behalf, or requests made before load. The network panel does.

How to Convert PDF to PNG Online — 3 Easy Steps
- Add a PDFChoose one PDF up to 50 MiB and 1,000 pages.
- Pick a resolutionThis is the only setting that changes the output. 1× is 96 DPI; 2× is 192 DPI and produces four times as many pixels.
- Convert and downloadPages render one at a time and arrive as a ZIP of PNG files in page order.

What This Tool Produces
- One lossless PNG per PDF page
- 96 or 192 DPI rendering
- Exact rendered pixels, with no encoding artifacts
- A ZIP with source-based page filenames
Controls and Method
Resolution
The whole control surface. A Letter page is about 816 × 1056 pixels at 1× and 1632 × 2112 at 2×.
No quality setting
PNG compression is lossless, so a quality dial would change file size without changing what you see — or change nothing at all. Offering one would be theatre.
No transparency setting
PNG supports an alpha channel, but a rendered PDF page does not use it. See the section below.
When PNG Earns Its Extra Size
PNG compresses by finding repetition, not by discarding detail. That makes it excellent at exactly the pages JPEG handles worst: charts, diagrams, tables with ruled lines, screenshots, logos, and any page built from vector shapes and flat colour. A page of black text on white can compress remarkably well, because there is very little variation to store.
It also makes PNG the right choice whenever the image is an intermediate rather than a final artifact. If the page will be cropped, annotated, re-scaled, or re-exported later, starting from a lossless PNG means each subsequent step works from the true pixels. Starting from a JPG means every step compounds the previous step’s losses.
The trade is size. On a photographic or heavily scanned page, PNG can be five to ten times larger than a reasonable JPEG of the same page — and it will not look better, because the detail JPEG discarded was invisible. For those pages, exporting as JPG is the honest answer.
PNG Supports Transparency. A Rendered PDF Page Does Not.
This is the most common misunderstanding about this conversion, and it is worth being blunt: exporting a PDF page as PNG will not give you a transparent background. PDF pages are rendered onto an opaque white canvas, because that is what a page is — the "white" of a PDF page is paper, not absence. Every pixel in the resulting PNG has an alpha value of 255.
If what you actually want is a logo or a diagram cut out of its page, the PNG export is only step one. Export the page, then remove the background from the image, or crop to the element first with the image cropper. Neither of those is something a page renderer can do for you, because it has no way of knowing which white is paper and which white is part of the artwork.
Resolution Is the Only Lever
Because there is no quality setting, choosing a resolution is the entire decision. The relationship is quadratic, not linear: doubling the DPI quadruples the pixel count, the file size, and the peak memory used while rendering.
| Setting | Pixel dimensions | Best for |
|---|---|---|
| 1× · 96 DPI | 816 × 1056 | Screen use, slide decks, documentation, web previews |
| 2× · 192 DPI | 1632 × 2112 | Print, retina displays, or anything that will be zoomed into |
What a PNG Cannot Carry Out of the PDF
Lossless refers to the pixels, not to the document. A PNG is a picture of a page, and it knows nothing about what the page contained.
- Text becomes a picture of text: not selectable, not searchable, not readable by assistive technology. No OCR runs.
- Vector artwork is resolved to pixels at the chosen scale. Zooming past that scale will show pixels, where the PDF would have stayed sharp.
- Links, form fields, buttons, annotations, and bookmarks survive only as their visual appearance.
- Tagged-PDF structure — headings, reading order, alt text — does not exist in a PNG.
- Embedded colour profiles are not carried across, so a wide-gamut document can shift slightly.
Practical Uses
- Put a chart or diagram from a report into a slide without it going fuzzy.
- Capture a page of a technical drawing for markup in an image editor.
- Produce reference images that will be cropped or annotated later.
- Archive a page image where no further compression loss is acceptable.
- Get a clean screenshot-quality page image without taking an actual screenshot.
Important Limitations
- Photographic and heavily scanned pages produce very large files for no visible gain over JPG.
- Vector sharpness ends at the chosen resolution; a PNG cannot be zoomed past it the way the PDF can.
- No OCR runs, so the output is never searchable or accessible text.
- Every page image is held in memory until the ZIP finishes, and 2× quadruples that footprint.
- Encrypted or password-protected PDFs are rejected rather than unlocked.
- The exported page is opaque white; the PNG alpha channel is present but unused.
Frequently Asked Questions
Will the PNG have a transparent background?
No. PDF pages render onto opaque white, so every pixel is fully opaque. To cut an element out of the page, export it here and then remove the background from the resulting image.
Why is there no quality slider?
PNG compression is lossless. A quality control would either do nothing or quietly change the format, and both would be misleading. Resolution is the only setting that changes the result.
My PNGs are enormous. What should I do?
Check what is on the page. If it is photographic or a scan, JPG at quality 85 will be a fraction of the size and look the same. If it is line art, try 1× instead of 2× before switching formats.
Is PNG better than JPG for PDF pages?
Neither is better in general. PNG wins on charts, screenshots, text, and line art. JPG wins on photographs and scans. The page contents decide, not the format.
Can I get vector output instead of pixels?
Not from this tool. Rendering to PNG resolves vectors to pixels at a fixed scale. If you need scalable artwork, keep the PDF, which is already a vector container.
Does 2× make blurry scans sharper?
No. It renders more pixels from the same source, so a low-resolution scan simply becomes a larger picture of the same blur. Resolution here is about the render, not the original.
