How to finish your task
Optimize supported JPEG objects and inspect the actual savings. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.
Practical example
Try a lower JPEG quality for a photo-heavy PDF. Check the original and output sizes and the number of optimized images.
Scope and limitations
Only supported RGB JPEG images are recompressed. PNG, CMYK and text-heavy PDFs may not shrink; the original is returned if there is no saving.
Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.
When is this useful?
Recompress supported JPEG objects in a photo-heavy PDF. Text-heavy or unsupported-image PDFs may not shrink.
Input and result example
photo-heavy PDF → optimized PDF or unchanged originalExamples illustrate the workflow; actual size, support and recognition depend on the source and settings.
