How to Make JPG Images Smaller After PDF Conversion
Reduce PDF to JPG file size using the Email preset, custom quality and an optional target size. Keep text readable while making images easier to share.
Start with the Email preset
Email & Compact uses 96 DPI and 70% JPEG quality. It creates fewer pixels than the 150 DPI Web preset and may be enough for a quick preview or attachment. Select only necessary pages: skipping unrelated pages reduces total download size without compressing the pages you keep.
Use the optional target size
In Settings, enter a target maximum per JPG in KB. The tool tries lower JPEG quality and, when necessary, smaller dimensions. This is a best-effort target, not a guaranteed exact size. Read any warning if a page cannot meet the target, and inspect the best available result.
Protect readability
Tiny text and dense tables may need the Web preset or a higher custom DPI. Compare text at the size the recipient will actually view. Reduce quality gradually rather than forcing a very small target. Custom settings allow 72–300 DPI and 40–98% JPEG quality.
Understand ZIP and estimates
ZIP groups images into one download; it is not a replacement for reducing image dimensions or JPEG quality. JPEG files are already compressed, so zipping them may save little space. The estimate before conversion is approximate; the Downloads section reports the actual combined image size. Target-size adjustment is unavailable for PNG and the fixed Presentation preset.
Frequently asked questions
Can I guarantee an exact JPG size?
No. The target is best effort; page content and minimum quality or dimensions can prevent a match.
Does ZIP make every JPG much smaller?
Usually not. ZIP is mainly a convenient package for images that are already compressed.
