Why PNG to JPG often saves a lot of size
PNG is lossless and is often unnecessarily large for photographic images. JPG is usually a better fit when the image does not need transparency and the goal is lighter uploads or faster sharing.
Convert PNG to JPG
Convert PNG images to JPG to reduce file size. Great for photos saved as PNG that don't need transparency.

The main caveat: transparency is lost
PNG to JPG is not a safe choice for logos, icons, or assets that rely on transparent backgrounds. If transparency matters, keep PNG or switch to WebP instead of JPG.
When PNG should stay PNG
Keep PNG when pixel stability matters, when the image will go through repeated editing, or when transparent regions are part of the design. JPG is best for photo-like content where smaller size matters more.
Known limitations
Before converting, note these constraints:
- Output behavior follows format capabilities (for example transparency support and lossy/lossless rules).
- Final file size depends on source image content and selected quality settings.
- If compatibility is critical, choose broadly supported targets first (typically JPG).

Frequently Asked Questions
Will I lose transparency?
Yes. JPG does not support transparency. Any transparent areas in your PNG will become white. If you need transparency, keep your image as PNG or convert to WebP.
Why is the output file sometimes larger than the original?
The output file becomes larger for three clear reasons: (1) Converting from a lossy format (JPG, WebP) to a lossless format (PNG) preserves every pixel, so file size increases in exchange for zero quality loss. (2) AVIF uses the AV1 codec, which has encoding overhead for small or simple images. AVIF delivers its strongest compression gains on high-resolution photos, with 20–50% better compression than JPEG in benchmark comparisons. (3) If the source is already heavily compressed, re-encoding does not reduce size further. PicShift uses industry-leading WASM encoders (MozJPEG, OxiPNG, libwebp) to produce the smallest possible output at your chosen quality. In compress mode, PicShift automatically keeps the original file when compression increases size. Learn more: https://picshift.app/docs/size-increase-explainer/
