Is PNG always clearer than JPG?
PNG avoids adding lossy JPEG artifacts to the rendered page, but source quality and the chosen resolution still limit detail. Output pages have an opaque background, even though PNG as a format supports transparency.

Sample checks you can repeat
Measured with the listed sample and settings; these may differ from this page’s starting preset. Timings are individual processing-function runs in the stated environment and exclude page loading. Library caches may be warm. These small-file checks do not establish performance or compatibility for every document.

Specific tasks
Using this tool
How to use pdf to png
- Select the PDF and enter page numbers or ranges, such as 1,3-5. Leave the field empty for all pages.
- Keep PNG selected and set a suitable longest edge in pixels.
- Render the pages and inspect text, lines, and overall page dimensions in the downloaded PNGs.
Before you start
What to keep in mind
- The longest output edge is 1,200–4,096 pixels. This renders the entire page onto an opaque background; it does not extract original embedded pictures or retain PDF transparency.
- Page images lose selectable text, links, editable form fields, bookmarks, accessibility structure and digital signature verification. No OCR is performed.
- A password can open supported protected PDFs for rendering. Some encryption, damaged files and unusual PDF features remain unsupported by the rendering library.
- Use at most 20 PDFs, 25 MiB per file, 80 MiB in total and 200 input pages across the batch. Choosing fewer output pages does not raise the input-page limit.
Use PNG when edges matter
A diagram, interface screenshot, or text-heavy page can benefit from PNG. Set the longest edge between 1,200 and 4,096 pixels and check small letters after export. Larger PNG pages use more memory and storage.
A rendered copy has a different purpose
Use the image as a preview or visual insert. The source PDF remains the better artifact for reading order, links, forms, and document-level verification.
Keep line art clear at the chosen resolution
PNG avoids introducing an additional JPEG-style lossy encoding step into the rendered page, which can suit line diagrams and interface documentation. The rendering resolution still matters. A low-resolution canvas cannot recover tiny text simply because its output format is lossless, and increasing the longest edge makes each page use more memory and storage. Choose a practical resolution for the actual destination.
For example, a 1600-pixel preview may suit an on-screen reference while a detailed drawing needs closer inspection at a larger setting. Render one representative page before processing a long selection. The output is a picture of the full page on an opaque background, not an extraction of its individual graphics or a transparent PDF layer. A PNG copy also loses searchable text, navigation links, form fields and document structure. Use it as a visual insert or preview while keeping the original PDF for reading and verification. If the resulting PNG is too large, reduce its display dimensions deliberately rather than relying on a JPEG quality slider that does not control PNG encoding.
Choose rendering resolution before lossless image encoding
PNG preserves the pixels supplied by the rendered canvas without a JPEG-style quality setting, but it cannot make that canvas independent of resolution. At the same longest edge, a page containing tiny dense text can still be unsuitable for close reading. The whole page, including its margins, occupies the selected pixel dimensions.
Start with one representative page and inspect its smallest relevant feature. Larger PNGs can consume substantial memory and storage, especially across a multi-page selection. This output has an opaque rendered background and no selectable text, links or form behavior. If a PNG is too large, consider a deliberate lower resolution or an allowed JPEG copy; the quality slider does not provide a lossless PNG byte target. Keep the PDF as the document master.
Common questions
About pdf to png
Does the JPG quality control reduce PNG size?
A lossy quality setting is not the same operation for PNG. Use appropriate dimensions and compare the actual output size.
Can a PNG page preserve searchable text?
No. Its letters are pixels. Keep the original PDF when text search or accessibility structure is needed.
Where are PDF pages rendered?
PDF.js and its worker render them locally in the browser. The worker and support files may need to load first; that is different from uploading your PDF to a rendering service.
Should the image replace the source PDF?
Usually it serves as a preview or visual insert. Retain the PDF for searchable text, links, navigation, accessibility information or document verification that an ordinary page image cannot provide.
