How to convert an image to JPG online
-
Load the file to convert
Click “Choose image”, drag the PNG or WebP onto the page, or paste it from the clipboard with Ctrl+V. With “Try a sample photo” you can test the tool even without a file of your own.
-
Set the JPG quality
Move the “Quality” slider and watch the Original/New comparison update live. For a faithful conversion stay between 85% and 92%; drop toward 75-80% only if file size is your top priority.
-
Check the preview
Review the result before saving: any transparent areas in the original appear on a white background, because JPG doesn't support transparency. If something looks off, “Undo” restores the initial file.
-
Download the JPG
Hit “Download” and get a ready-to-use .jpg file, with no watermark and no sign-up. You can start over with another image right away.
When JPG is the right choice
JPG is the photographic format par excellence and, above all, the one that works everywhere: company software, government portals, print kiosks, old versions of Office, any phone or TV. If an online form accepts “JPG/JPEG only”, this tool solves the problem in ten seconds. It's the right pick whenever the content is a photograph — people, landscapes, products — because its compression was built precisely for the continuous tones of real-world shots. It does have two limitations worth knowing: it doesn't support transparency and it's a lossy format, so it's not ideal for logos and sharp-edged graphics, where a lossless PNG keeps everything crisper. For a full comparison of the formats, see the guide to JPG, PNG and WebP.
From PNG to JPG: how much space you save
A photograph accidentally saved as PNG is one of the most wasteful files there is: PNG preserves every single pixel losslessly, and on a color-rich shot that means enormous files. Converting it to JPG brings a dramatic drop in size:
- 4.8 MB photographic screenshot in PNG → about 600 KB as JPG at 85%
- 12 MB smartphone photo exported as PNG → about 1.5 MB as JPG
- 8 MB color document scan → under 1 MB
We're talking typical reductions of 80-90%, visible immediately in the Original/New comparison. If you want to shave off a few more KB after converting, run the result through the tool to compress images and fine-tune the slider until you hit the size you need.
What happens to transparency
The JPG format has no alpha channel, so it can't store transparent pixels. When you convert a PNG or WebP with a transparent background, this tool flattens the empty areas onto a white background: it's the most predictable behavior and the one that looks best in documents, emails and prints. Keep that in mind for logos: a mark designed to sit on colored backgrounds will carry a white rectangle with it once it's a JPG. The same goes for images with rounded corners: the softened corners stay visible only as long as the file keeps its transparency, so in those cases stick with PNG. The practical rule is simple: if the image needs to “blend” into the page background, no JPG; if it just needs to be viewed or printed, white works fine.
A conversion that happens on your device
The JPG conversion runs on the browser's Canvas API: the file is read, drawn onto a virtual canvas and re-exported as a JPEG at the quality you chose. No data travels to outside servers — the entire conversion takes place on your computer or phone, which is why it feels instant even on slow or absent connections. The re-encoding produces a clean file, stripped of the original's EXIF metadata, and handles images up to 4096 pixels on the long side. A pro tip: always convert from the best file you have. JPG is a lossy format, so every subsequent re-save degrades the image a little; if you're planning more edits, resize or adjust first, and leave the JPG conversion as the last step in the chain.
