FAQ
How do I convert a PDF to an image?
Open the home page, drag your PDF onto the upload area or click it to browse for a file, then choose an output format and scale. Press the convert button and every page is rendered and packed into a ZIP archive, which your browser downloads automatically. The whole process runs on your own device.
Are my files uploaded to your server?
No. Your PDF is read and decoded inside your browser and is never transmitted to this site or anywhere else. The rendering engine is PDFium compiled to WebAssembly, so it runs locally rather than on a server. Once the page has finished loading you can disconnect from the network entirely and the converter will still work.
Do I need to create an account?
No. There is no registration, no login and no paid tier. Every feature is available immediately to anyone who opens the page.
Which image formats can I export to?
PNG, JPG and WEBP. PNG is lossless and best for text and diagrams, JPG is the most widely compatible and suits scans and photographs, and WEBP generally produces the smallest files at a given visual quality. The source file must be a PDF; other document formats are not supported.
Where is the converted file saved?
Wherever your browser normally puts downloads, which on most systems is the Downloads folder. The converter hands the finished archive to the browser as an ordinary download, so any custom download location you have configured is respected. Nothing is stored on this site.
Why do I get a ZIP file instead of images?
A PDF usually has more than one page, and a ZIP keeps all the resulting images together as a single download instead of triggering one download prompt per page. Inside the archive each file is named after your original document with the page number appended, so the original order is preserved. Any operating system can open a ZIP without extra software.
Is there a file size or page limit?
There is no limit imposed by this site, because there is no upload and no server-side processing to pay for. The practical ceiling is your device's memory: each page is rendered into a full-size bitmap before being encoded, so a very long document at a very high scale can exhaust what the browser will allocate. If a large file stalls, lower the scale or split the PDF into smaller parts.
Why does my exported image look blurry?
The scale setting is almost certainly too low. Scale 1x renders at roughly 72 pixels per inch, which is thumbnail quality. Raise it to 2x for comfortable on-screen viewing or 4x and above for printing. Increasing image quality will not help here, because the encoder cannot add detail that was never rendered.
What does the scale setting mean in DPI?
A PDF page is measured in points, and one point is 1/72 inch, so scale 1x corresponds to 72 DPI. Multiply the scale by 72 to get the effective resolution: 2x is 144 DPI, 4x is 288 DPI, and 10x is 720 DPI. Keep in mind that scale affects both width and height, so doubling it roughly quadruples the pixel count and the file size.
What does the image quality slider affect?
It sets the encoder quality for the lossy formats, JPG and WEBP, on a scale from 0.1 to 1.0. Values around 0.85 to 0.9 are usually indistinguishable from maximum while producing considerably smaller files. The setting has no effect when PNG is selected, because PNG is lossless.
What does the ZIP compression slider do?
It sets the deflate level used for the ZIP archive that wraps your images, not for the images themselves. Since PNG, JPG and WEBP are already compressed formats, there is little redundancy left for the ZIP to remove, so raising this slider usually costs processing time without saving meaningful space. A low value is normally the better choice.
Can I convert only some of the pages?
Not at the moment. The convert button processes the entire document, although the preview area does let you page through the file to check it before converting. If you need a subset, split the PDF beforehand with another tool. Page range selection is a frequently requested feature and is being considered.
Does it work on a phone or tablet?
Yes, on any modern mobile browser. Bear in mind that phones and tablets have considerably less memory available to a browser tab than a desktop machine, so very long documents or very high scale values are more likely to fail there. Lowering the scale usually resolves it.
Why is there a loading spinner when the page opens?
The spinner appears while your browser downloads and initialises the WebAssembly build of the PDF rendering engine, which is a few megabytes. This is what makes local conversion possible, and it only has to happen once because the browser caches it afterwards. Subsequent visits are much faster.
Is the converter really free?
Yes, and there is no usage limit or hidden paid tier. The site is funded by advertising, which covers hosting and lets the tool stay free for everyone. Because conversion happens on your device rather than on a server, the running cost of each conversion is effectively zero for us.
