PNG to JPG Converter
Shrink a bulky PNG into a compact JPG. Upload your image below, pick a quality level, and download a file that's often a fraction of the original size — ideal for email attachments, uploads with size limits and faster web pages.
JPG is the right choice for photographs and complex images where a large PNG buys you nothing visible. Filembly's quality slider lets you choose your own balance between size and fidelity.
How the PNG to JPG conversion works
Your PNG is decoded and re-encoded as a JPG using the mozjpeg encoder, which squeezes out noticeably smaller files than standard JPEG encoders at the same visual quality. Because JPG has no transparency, any transparent areas in your PNG are flattened onto a white background. The default quality of 85 is visually excellent for most images; lowering it shrinks the file further.
How to convert PNG to JPG
- Upload your .png image above.
- Confirm JPG as the destination and adjust the quality slider if you like (85 is a good default).
- Click Convert.
- Download the compressed JPG.
Limitations to know about
- Transparency is lost — JPG doesn't support it. Transparent regions become white. If you need transparency, convert to WEBP instead.
- JPG is lossy: fine detail, sharp text edges and flat-color graphics can show artifacts, especially at lower quality settings. For screenshots and logos, PNG or WEBP are usually better.
Privacy and security
Your file is uploaded over HTTPS, converted entirely in memory and streamed straight back to your browser. It is never written to disk, never logged and never retained after the conversion — there is nothing to delete because nothing is stored. Files are validated by extension, type and content signature, and uploads are never executed. Read more in our privacy policy.
Frequently asked questions
What happens to transparent backgrounds?
JPG has no alpha channel, so transparent areas are flattened onto a solid white background. If your image needs transparency — logos, cut-outs, overlays — convert it to WEBP instead, which supports transparency at small file sizes.
What quality setting should I use?
85 (the default) is visually indistinguishable from the original for most photos. Use 70–80 when file size matters more, and 90+ only when the image will be inspected closely — beyond that, files grow quickly with little visible gain.
How much smaller will my file get?
It depends on the image, but photographic PNGs commonly shrink by 70–90% when converted to JPG at quality 85. Graphics with large flat areas compress less dramatically and may look better left as PNG.
