How to convert a PDF to images
- Drop in the PDF you want to turn into images.
- Pick the format and the resolution — 150 DPI is right for most things, 300 for print.
- Press Convert. One page downloads as a single image; several arrive together in a ZIP.
Questions people ask
Which format should I choose?
JPG for pages that are mostly photographs or scans, because it compresses continuous tone well. PNG for pages that are mostly text, line art or diagrams — it is lossless, so text edges stay sharp instead of picking up the fuzzy halo JPG gives them. WebP splits the difference and produces the smallest files of the three, but a few older programs still will not open it.
What resolution do I need?
72 DPI matches the PDF’s own internal units and is fine for a quick on-screen preview. 150 DPI is the sensible default for sharing or viewing on a modern display. 300 DPI is the standard for printing and for running text through OCR. Higher than that mostly produces enormous files without visible benefit, since most PDFs do not contain that much real detail to begin with.
Why is my file so large at 300 DPI?
An A4 page at 300 DPI is about 2480 × 3508 pixels — roughly 8.7 megapixels per page. That is simply a large image. If the result is bigger than you want, drop to 150 DPI, or switch to JPG and lower the quality slider, which usually cuts the size by more than half with no visible difference on screen.
Will the text still be selectable?
No, and this is worth understanding before you convert. A PDF holds text as text; an image holds it as pixels. Converting is a one-way trip — the result cannot be searched, selected or copied, and it cannot be converted back into real text without OCR. If your goal is simply to stop people editing the document, that is what the watermark and permission tools are for.
Can it handle a password-protected PDF?
If the PDF only restricts editing or printing, it opens normally. If it needs a password just to be viewed, you will need to remove that first with the Unlock PDF tool, which requires knowing the password.
How many pages can it manage?
Each page is rendered and encoded one at a time and then released, so a long document works — it just takes proportionally longer. Very large documents at 300 DPI can use a lot of memory while the ZIP is assembled, so if a 500-page file struggles, convert it in batches using the page range box.
Is my document uploaded?
No. The pages are rendered on your own device.
