How to convert an image to JPG online

  1. 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.

  2. 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.

  3. 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.

  4. 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.

Frequently asked questions

How are images with transparency handled?
Transparent areas are filled with white, because JPG has no alpha channel. The result is perfect for documents and prints, less so for graphics meant to sit on colored backgrounds: in that case it's better to stay with PNG, which preserves transparency without compromise.
What quality value should I set?
For a conversion whose goal is simply changing format, keep the “Quality” slider between 85% and 92%: the file stays light and the difference from the original is imperceptible. Drop to 75-80% only when size matters most, for example for email attachments or uploads to portals with tight limits.
Can I convert a WebP to JPG?
Yes, and it's one of the most common uses: many images downloaded from the web come as WebP, and some older programs won't open them. Drag the file into the tool, set the quality and download the .jpg — it will open anywhere, from Photoshop circa 2010 to the office management system.
Does JPG lose quality with every save?
Yes, JPG is a lossy format and every re-encode introduces small artifacts that accumulate. The first conversion done at high quality is effectively invisible; degradation only shows after saving and re-saving many times. The rule: make all your edits first, and convert to JPG once, at the end.
How do I reduce the file size further after converting?
You have two complementary routes: lower the quality with the tool to compress images online, or reduce the pixels if the image is bigger than you need. The second is often the more effective: halving a photo's long side cuts its file size by roughly three quarters.
