PDF to JPG Troubleshooting: Files, Previews and Downloads
Fix common PDF to JPG problems with file limits, reader errors, previews, memory and ZIP downloads. Keep completed images when cancelling a job.
A PDF will not load
Check the limits: each PDF must be no more than 50 MB and 100 pages, and a batch supports up to 10 PDFs and 150 MB total. A renamed file is not necessarily a valid PDF. Try opening it in a PDF reader first and provide its password if requested. A corrupted or unsupported file may need a new copy.
The reader or preview fails
For a reader-start error, refresh the page and use a current browser. If you operate this website, a worker-file fetch error can also indicate a deployment or caching problem. A failed preview can be retried by selecting the page again; allow the visible thumbnails time to render.
A large conversion runs out of memory
Select fewer pages, choose a lower-resolution preset and close other heavy tabs. Page dimensions matter as well as PDF file size. The converter rejects images above its canvas limits; higher DPI increases working memory. Escape or Cancel stops the job while keeping completed images available.
A download seems missing or damaged
Check the browser’s downloads list and device storage. Wait for ZIP preparation to finish before opening the archive, and extract it with an archive app. If ZIP creation fails, download completed images individually. Folder saving is available only in browsers with the required directory-picker support; ZIP remains the fallback. Avoid closing the page until your files are saved.
Frequently asked questions
Why can a small PDF still use lots of memory?
A PDF with large page dimensions can render into a huge pixel image even when its source file is small.
What remains after I cancel?
Completed images remain available for download; an incomplete ZIP is not offered as a finished archive.
