Why Convert PNG to JPG
PNG's lossless compression keeps every pixel exact, which is great for graphics and screenshots but produces much larger files than necessary for ordinary photos — JPG's compression can shrink a photo to a fraction of the size with minimal visible difference.
Many upload forms, email attachments, and older systems have file-size limits or simply expect JPG by default, making conversion a common first step before sharing a photo that started life as a PNG (often from a screenshot or export tool).
Since JPG has no transparency support, any transparent areas in your PNG are filled with a solid background (white by default) during conversion — worth checking your source image for transparency before converting if that matters to you.

Frequently Asked Questions
What happens to transparent areas in my PNG?
JPG doesn't support transparency, so any transparent or semi-transparent pixels are filled with a solid background color (white by default) during conversion.
Why is my conversion sometimes reported as lower quality?
JPG uses lossy compression, so some detail is discarded to reduce file size — our default settings balance visual quality against size, but very high-frequency detail (like sharp text or fine line art) can show minor compression artifacts.
How much smaller will the JPG be?
It depends on the image content, but photos typically shrink significantly — often 50-90% smaller than the equivalent lossless PNG, since JPG compression is specifically tuned for photographic detail.
Is PNG-to-JPG a good idea for screenshots and graphics with text?
For photos, yes. For screenshots, logos, or graphics with sharp edges and text, PNG's lossless compression usually preserves crisper detail — only convert to JPG if file size matters more than perfect sharpness.
Can I just rename a PNG to JPG?
No — changing the file extension only relabels the file; the data inside is still PNG, so it stays large and can fail to open in apps that expect a real JPG. A proper conversion actually re-encodes the image as JPG.
Can I convert PNG to JPG on iPhone?
Yes — the converter runs entirely in your browser, so just open this page in Safari or Chrome on your iPhone (or Android), upload the PNG, and download the JPG. There's no app to install.
Is there a file size limit?
50MB free, 100MB for registered accounts.
