Presets
Quality is the main file-size control. Lower quality usually creates smaller JPG files.
Maximum quality: minimal compression. File size reduction may be small.
Exact reduction depends on the image. Photos compress more than flat graphics in many cases.

Real use cases for PNG to JPG
You need quick email attachments from design exports
Flatten PNG exports into JPG for smaller attachment sizes and broader recipient compatibility across email clients.
A CMS image field only accepts JPG
Legacy CMS installations often assume JPEG uploads. Convert and continue without changing the publishing stack.
You are optimizing non-transparent screenshots for docs
When alpha is unnecessary, JPG usually reduces byte size for inline documentation and knowledge-base pages.
PNG to JPG tradeoff table
PNG to JPG is a practical compatibility and file-weight tradeoff. It is usually chosen when transparency can be discarded.
| Decision point | Keep PNG | Convert to JPG | Use this when |
|---|---|---|---|
| Transparency | Supported | Not supported | Convert only when transparent regions are not required. |
| Typical file size | Can be heavy for photos and large graphics | Often lighter with lossy compression | Use JPG for upload limits and bandwidth-sensitive channels. |
| Visual fidelity | Lossless | Lossy at lower quality values | Use balanced quality for readable text and edges. |
| Platform acceptance | Strong support | Very broad support | JPG remains the safest fallback for legacy pipelines. |
Pitfalls to avoid
Transparent areas become solid
PNG alpha is removed in JPG output. If transparency matters, keep PNG or switch to WebP instead of JPG.
Text and UI edges may soften
JPG compression can blur sharp lines in interface screenshots. Validate small text after conversion.
Background color assumptions
If a transparent logo is flattened for JPG, ensure the chosen background still matches where the image will be displayed.
