Which Format When

JPG for photographs — smallest at high visual quality, but no transparency and lossy on every re-save. PNG for screenshots, logos and anything needing transparency — lossless, larger files. WebP does both jobs 25-35% smaller and is supported by every modern browser — the right choice for the web today.

Conversion happens on a canvas in your own browser: files never leave your device, there is no size limit beyond your device's memory, and it works offline once the page loads. Converting to JPG flattens transparency onto a white background.

Frequently Asked Questions

Does converting JPG to PNG improve quality?

No — compression artifacts already baked into the JPG stay. PNG only prevents further loss on subsequent edits. Convert in the quality-losing direction (PNG→JPG/WebP) only once, at the end of editing.

Why is my PNG bigger than the JPG it came from?

PNG is lossless: it faithfully stores the photo including JPG noise, which compresses poorly. For photos, PNG is nearly always the largest option.

Is anything uploaded?

No. The file is read locally, drawn to a canvas and re-encoded by your browser. You can watch the network tab — no requests carry your image.
