When to convert a PDF to an image
Attach a specific page to an email, post a preview of a document in a chat, drop a slide into a presentation, extract the image from a signed contract, run OCR on one page. In all those cases, grabbing one or a few pages of a PDF and having each one as a standalone JPG is the direct path.
Why "no upload" changes everything
Practically every online PDF-to-image converter works the same way: you upload the PDF, a server processes and returns images. That means your file left your machine and passed through third-party infrastructure with a retention policy you do not control. For a public PDF, fine. For a contract, a medical report, a tax receipt, material under NDA — not.
Here the PDF is read into browser memory, rendered onto a canvas page by page and exported as JPG/PNG on your machine. No upload, no queue, no cloud copy.
Which DPI to use
- 72 DPI — web, screen preview, a corporate email attachment. Small file, text legible but not crisp in print.
- 108 DPI — high-density screen (Retina, Full HD). A balance between weight and sharpness.
- 150 DPI — screen reading, print preview. Recommended for most cases.
- 300 DPI — printing. Sharp text, no jagged graphics. The file is ~4x larger than at 72 DPI.
Password-protected PDFs
PDFs that require an open password cannot be converted without it. The tool detects them and warns — it does not try to guess. If you need to extract pages from a protected PDF, open it in your reader (Acrobat, Preview, browser) with the password, save an unlocked copy, and bring it here.
JPG or PNG?
JPG is the choice for most documents. At 90% quality the visual loss is imperceptible and the file is 3-5x smaller than PNG. For PDFs with fine text, graphic lines, icons, or that you will still edit, PNG (lossless) is better. In a large batch, JPG is almost always the right call.
To shrink the generated images further, run them through our image compressor — resizing to 1920 px wide and saving as WebP 80 halves the weight with no visible loss.
## faq
Frequently asked questions
Is the PDF uploaded to a server?
No. The PDF is read by the browser, rendered page by page onto a canvas and exported as JPG or PNG on your machine. There is no upload, no queue and no cloud copy — important when the document is a contract, a medical report, a receipt, material under NDA. Disconnect from the internet after loading the page and the conversion still works.
Image quality — does it match the PDF?
Each page is rasterised at the resolution you pick. 150 DPI is enough for screen reading; 300 DPI leaves the JPG sharp enough for printing. Above 300 DPI the file grows fast with no visible gain. At 150 DPI, an A4 page produces a JPG of roughly 1240 × 1750 px.
Can I convert only some pages?
Yes. After the conversion, every page appears as a thumbnail with a checkbox. Deselect any you do not want to include in the ZIP. All pages are selected by default.
Password-protected PDF — does it work?
No. The tool detects PDFs that require an open password and warns you. We do not implement decryption in this release (claiming it works without the password would be dishonest). If you need to extract pages from a protected PDF, open it in your reader (Acrobat, Preview, browser) with the password, save an unlocked copy, and bring that here.
Is there a size or page-count limit?
No limit is imposed by the tool, because there is no server. The ceiling is your browser memory. A 100-page PDF may take 10-15 seconds on desktop and a few minutes on an older phone — each page is rendered one at a time, in series, precisely to avoid blowing up memory. PDFs of 500+ pages are doable but heavy.
JPG or PNG — which should I use?
For document PDFs (contracts, reports, receipts) JPG at 90% produces a much smaller file with no visible quality loss. For PDFs with fine text, graphic lines, icons, or that you will still edit, PNG (lossless) is better — the cost is a 3-5x larger file. In a batch, JPG is almost always the right call.
Do the fonts in the PDF come out correctly?
Yes. pdfjs loads the fonts embedded in the PDF and re-draws them on the canvas. If the PDF references an external font (rare today), the browser falls back to a similar font — the conversion does not fail, but specific glyphs may look somewhat different.
