How to use the pdf to jpg
- 1Drop your PDF into the box above.
- 2Choose JPG or PNG and set the resolution in DPI.
- 3Press Convert to images and wait while each page is rendered.
- 4Download pages individually, or build a ZIP of all of them.
Choosing a resolution
DPI here means dots per inch relative to the page's physical size, so the pixel dimensions depend on both the DPI and the page. An A4 page at 150 DPI comes out around 1240 × 1754 pixels; at 300 DPI it is 2480 × 3508.
For on-screen use — pasting a page into a slide deck, posting an excerpt, embedding in a document — 150 DPI is ample and keeps the files manageable. For printing, 300 DPI is the traditional standard and the point beyond which most people cannot see improvement in normal viewing.
Above 300 DPI the returns diminish sharply while memory use does not. Rendering at 600 DPI produces images four times the area of 300 DPI, and on a long document that is enough to exhaust a phone browser's memory. Go high only when you have a specific reason, such as reproducing fine engineering line work.
JPG or PNG?
The right answer depends entirely on what is on the page. PNG is lossless, so text edges stay perfectly crisp — but a page of text as PNG can easily be several megabytes, because lossless compression cannot do much with the fine detail of antialiased type.
JPG is dramatically smaller on pages that are mostly photographic. On pages that are mostly text it produces visible ringing artefacts around the letters, especially at quality settings below 85. For a text document at 150 DPI, quality 90 JPG is usually a good compromise; below that the text starts to look soft.
A practical rule: scanned photographic documents and image-heavy pages go to JPG; text documents, diagrams, tables and anything with a transparent-looking white background go to PNG if size allows.
What you lose by converting
Everything that made it a PDF. Text becomes pixels, so it can no longer be selected, copied, searched or read by a screen reader. Vector graphics are flattened, so zooming past the render resolution shows pixelation where the original would have stayed sharp. Links, form fields, annotations and bookmarks all disappear.
This is sometimes exactly what you want. Converting to images is a reasonable way to stop casual copying of a document, to guarantee that it displays identically everywhere regardless of missing fonts, or to get a page into a system that only accepts images.
It is not a security measure, though. The text is still legible to any OCR tool, and OCR is now good enough that treating rasterisation as protection is a mistake.
Downloading a whole document
Each page appears with its own Save button, which is convenient for a handful of pages. For a longer document, use the ZIP option: it packages every rendered page with zero-padded, sequentially numbered filenames so they sort correctly in any file manager.
The ZIP is assembled in your browser using JSZip, so it is subject to the same memory limits as everything else here. A 200-page document at 300 DPI produces a very large archive; if the tab struggles, render at a lower DPI or split the document first.
One detail that saves trouble later: the filenames inside the archive are numbered with leading zeros, so page 2 becomes page-002 rather than page-2. Without that padding, a file manager sorting alphabetically puts page 10 immediately after page 1, which quietly scrambles the order of any document longer than nine pages.
Frequently asked questions
What DPI should I use?
150 for screen use, 300 for printing. Higher settings multiply memory use quickly with little visible benefit.
Which format is better, JPG or PNG?
PNG for text, diagrams and line art; JPG for scanned photographs and image-heavy pages where file size matters.
Can I convert only one page?
Every page is rendered, but you can download just the ones you want. To render fewer pages, extract them first with the Split PDF tool.
Will the text still be searchable?
No. Converting to an image turns text into pixels. Searchability requires OCR, which this tool does not perform.
Why did my browser run out of memory?
High DPI on a long document. Every page is held as a full-resolution bitmap. Lower the DPI or split the document into sections.
Is my PDF uploaded?
No. Rendering is done locally by pdf.js in your browser.
