Simple 3-step flow
Drop up to 30 PNG files, tune once, and download JPG files plus one ZIP — decoded and re-encoded in this tab.
01
Drop up to 30 PNG files from this device. Each shows as a preview card with a live size estimate. Drag to reorder.
Batch of 30 · drag to reorder
02
Drag quality from 10 to 100, then hit Convert. Your browser decodes the PNG and re-encodes it as JPG on a canvas locally.
Slider drives the trade
03
Save each JPG individually or grab one ZIP for the batch. The sources on disk stay put.

What the workspace does
These match the converter — the pair rule, the quality rule, and local-only processing.
Transparency flattens to white — PNG alpha does not survive JPG.
PNG → JPG
Quality runs 10 to 100 — lower is smaller, higher keeps detail. The estimate is honest because JPG is lossy.

Privacy architecture
Cloud converters upload the image to flip its format remotely. This one decodes and re-encodes on a canvas here — the file never leaves the device.

Honest output
Format conversion changes the container and compression — it never invents pixels, transparency, or detail.
Answers
Quality, transparency, and whether PNG files are uploaded.
Because JPG cannot store transparency at all. Every transparent pixel has to be replaced with a real colour, and this converter uses white. Convert to WebP instead if you need the transparency preserved.
No — there is no colour picker. Transparent pixels are always flattened to white before encoding. Convert to WebP if you need transparency preserved.
No. Once the alpha channel is gone it is gone, and the white pixels are now ordinary image data. Keep your original PNG.
For photographs, usually by a large margin. For flat graphics and screenshots the saving is smaller, and JPEG artefacts around sharp edges may not be worth it.
Yes — up to 30 PNGs per batch, each with its own estimate and download plus one ZIP. Transparency flattens to white on every file.
Constraints
JPG cannot store transparency — flattened to white, no colour picker.
Up to 30 images per batch — each with its own download, plus ZIP.
