How to convert a PNG image to JPG
PNG and JPG serve different purposes — PNG keeps every detail (lossless) and supports transparency, while JPG compresses more aggressively and produces much smaller files for photos.
Why convert
- A PNG photo is often far larger than the same photo as JPG, with no visible quality difference at normal viewing size.
- Some forms and portals only accept JPG.
How to convert
Upload the PNG to Image Compress or the Image Editor and choose JPG as the output format when downloading.
What you lose
JPG doesn't support transparency — any transparent area in the PNG becomes solid white (or another background colour) once converted. If you need to keep transparency, stay with PNG or convert to WebP instead.
Batch converting several images
If you have many PNG photos to convert at once, processing them individually through Image Compress with JPG selected as the output format works, though for very large batches, dedicated batch-conversion software may be faster.
Checking the result
After converting, open the JPG and confirm any text or fine detail that mattered in the original is still legible — JPG's compression can slightly soften very fine text, which matters for screenshots more than photographs.
Keeping a PNG master copy
If the PNG was your original, higher-quality version, keep it as your archive copy and treat the JPG conversion as a distribution copy for wherever a smaller file is needed — this way you can always re-export a fresh JPG later rather than working from a copy of a copy.

If you are not sure whether a specific image genuinely needs to stay as PNG, ask whether it has flat colours and sharp edges (keep as PNG) or is a photograph with lots of natural colour variation (JPG usually serves it just as well, at a fraction of the size).
