About PDF to JPG
Converting a PDF page to a JPG is rasterisation: the page description — glyph runs, vector paths and embedded images — is drawn onto a pixel grid by pdf.js in your browser. It creates a picture of the page, not a guarantee of an exact match to every PDF viewer; fonts, document features and browser rendering can affect appearance. Two independent settings decide the outcome. Resolution comes first: DPI sets the scale of the pixel grid using the page's PDF bounds and rotation, with pixel dimensions rounded down. An A4-sized page at 150 DPI is roughly 1240 × 1754 pixels, and at 300 DPI roughly 2480 × 3508. Quality comes second: JPEG is lossy, and its quality slider controls encoding that can introduce fringing or blocking around sharp text. Higher DPI cannot undo low-quality encoding, and higher quality cannot restore detail absent from the render. Start at 150 DPI and 82%, then inspect the result at the size you need. Text stops being selectable once it is pixels, and transparent areas are rendered against white. One successful page downloads directly; several successful pages are bundled in a ZIP. Check warnings for skipped pages and use the original, unpadded page numbers in filenames rather than assuming an archive listing is in numeric order.
How to PDF to JPG
- 01
Add your PDF
Add one accessible PDF, up to 250 MiB. It is opened and rendered locally without uploading the file. There is no password-entry flow; use an accessible local copy.
- 02
Choose resolution and quality
Pick a DPI for the pixel dimensions, then set JPEG quality for the compression trade-off. Start at 150 DPI and 82%, and inspect small text at the size you will use.
- 03
Narrow the page range if you want
Leave the page field on “all”, or list specific pages such as 1, 4-8, 12.
- 04
Convert and download
Download one successful image directly, or a ZIP when several pages succeed. Read skipped-page warnings; filenames keep source page numbers without zero-padding, so sort numerically if needed.
What this tool does
- Five DPI presets from 72 to 300; actual pixel dimensions follow the PDF page's bounds and rotation
- JPEG quality exposed as its own control rather than hidden behind a vague “quality” preset
- Page ranges, so a 400-page report need not become 400 images
- Pages rendered locally in your browser with pdf.js
- One successful image downloads directly; several are zipped with unpadded source page numbers in their filenames
Limitations worth knowing
Every PDF tool has constraints. Stating them plainly is more useful than discovering them halfway through your work.
- JPEG is lossy. Text fringing or blocking depends on the page, DPI, quality and browser encoder, not a fixed quality threshold. Use PDF to PNG to avoid lossy pixel encoding.
- The output is an image, so text is no longer selectable, searchable or copyable.
- JPEG has no transparency. Transparent regions are composited onto white.
- High DPI, large pages and long documents can exhaust browser memory, even within the file-size limit. Failed pages may be skipped.
How your file is handled
This tool runs entirely inside this browser tab. When you choose a file, your browser reads it from your own disk and hands the bytes to JavaScript running on this page — no network request carries your document anywhere. You can confirm that yourself: open your browser’s developer tools, switch to the Network panel, and run the tool. You will see no upload.
Nothing is stored after the fact. Closing or reloading this tab discards the file, the result and everything derived from them, because none of it ever left your machine. Read how local processing works.
Questions about PDF to JPG
What pixel size will I get?
The renderer scales the PDF page viewport by DPI divided by 72, accounts for its bounds and rotation, and rounds pixel dimensions down to whole pixels. An A4-sized page is roughly 1240 × 1754 px at 150 DPI or 2480 × 3508 px at 300 DPI; exact dimensions depend on the PDF. An unrotated US Letter page at 150 DPI is 1275 × 1650 px.
What is the difference between DPI and the quality slider?
DPI decides how many pixels are drawn. Quality decides how much of that pixel data JPEG throws away to shrink the file. They are independent, and raising one cannot fix the other.
Why does the text in my JPG look slightly fuzzy?
Low DPI can draw glyphs with too few pixels, and low JPEG quality can smear high-contrast edges. The source document and font rendering can also affect the result. Try 220 DPI and 90% quality, compare at the intended viewing size, or use PNG to avoid JPEG encoding artefacts. Higher settings do not guarantee viewer-identical text.
Can I get the text back out of the images?
The JPG contains pixels, not the PDF's selectable text layer. Extract text from the original PDF with PDF to Text when it contains real text. If the page is a scan or only the image remains, use a separate OCR tool and check its recognition results; this converter does not perform OCR.
Are the pages uploaded to render them?
No. Rendering and encoding happen locally in your browser without uploading the PDF. One successful page downloads as an image; several are assembled into a ZIP in memory. Engine or worker assets and optional consented aggregate reporting can still make network requests, so local file processing does not mean a silent network panel.
