Common problems and solutions for turning images into PDFs in Sejda

Small issues can occur while using any online tool, especially when working with multiple images. Sejda usually performs well, but factors like file size or image quality can sometimes affect the results during JPG to PDF conversion. Below are some common problems you may face, along with their solutions.

Upload fails: Check file size limit

Upload may fail when your images are too large or exceed the tool's limit. Try reducing image size or compressing files before uploading. You can also upload fewer images at a time to avoid errors. This makes the process smoother and prevents repeated failures during conversion.

Images not loading: Refresh browser or retry upload

If images don't show, it may be a temporary glitch in the browser or a slow connection. Often, the problem can be resolved in a rapid time by refreshing the page. Close the browser and reopen if necessary, and upload again. This allows the proper load to be restored and stability to be enhanced.

Poor quality output: Use high-resolution JPG files

The PDF is likely to be blurry or pixelated if the images used to create it were not of high quality. Use clear, crisp, high-quality JPG images first. This way, your final PDF will look sharp and professional. The quality of the images also enhances the readability and visual appeal of the document.

Wrong order: Rearrange images before conversion

Images may not always stay in the correct sequence after upload. You can fix this by dragging and dropping thumbnails in the right order. Checking the order before converting keeps your PDF organized. This ensures your final document flows correctly and looks properly structured.

Conversion error: Clear cache and try again

Conversion errors often happen due to stored browser data or temporary glitches. Clearing your cache can remove these hidden issues. After that, reload Sejda and try the process again. This simple step often restores smooth performance and fixes unexpected technical problems.

Missing pages: Ensure all images are selected

Sometimes a file may not be included if it was not properly selected during upload. Always review your uploaded list before starting conversion. This helps make sure no page is missing in the final PDF. Careful checking prevents incomplete documents and repeated work.

Slow processing: Reduce the number of images

Processing can slow down when too many images are added at once. Split your files into smaller batches for faster results. This makes the process smoother when you turn PNG to PDF with Sejda. It also improves speed and reduces system load during conversion tasks.
