Why Convert JPG to PNG?

JPG compression introduces blocky artifacts on images with sharp edges, text overlays, and solid-color regions.

PNG uses lossless compression that preserves every pixel exactly, making it the standard for logos, UI screenshots, and graphics where color accuracy matters more than file size.

Frequently Asked Questions

Will converting JPG to PNG improve quality?
No. Converting JPG to PNG stops further quality loss but does not restore detail already lost by the original JPG compression. Use PNG from the start when quality is critical.
Why is my PNG file larger than the original JPG?
PNG is lossless and stores pixel data more completely than JPG, so the file size is almost always larger. This tradeoff is intentional when you need exact pixel fidelity.
Does PNG support transparency?
Yes. PNG supports full alpha channel transparency, which is why it is the standard format for logos, icons, and UI graphics where a transparent background is needed.
Can I batch-convert JPGs to PNG in the browser?
The browser converter handles one file at a time. For dozens of files, the TeraConvert desktop app converts the whole batch at once.
Is my file private?
Yes. The conversion runs in your browser tab and nothing is uploaded, so your files never leave your device. The only limit is size: 25 MB for this format. Bigger files route to the desktop app.

Batch-converting a product image library?

TeraConvert Desktop converts a whole batch natively using macOS sips, with no 25 MB browser cap.
