Convert images to JPG
JPG is still the format every phone, website upload form, printing service and office app accepts without complaint. This converter turns WebP, PNG, JFIF, AVIF, GIF and BMP files into JPG in your browser, and HEIC photos too wherever your browser can open them. You decide the trade-off between quality and file size with a slider and see the new size for every image before you download. Transparent PNG or WebP graphics get a background color of your choice instead of turning black. Presets cover the common jobs: high quality for printing, a balanced setting for everyday sharing, small files that fit in an email and a 1080-pixel size for social media. Convert up to 30 images at once and save them as one ZIP.
Questions
How do I convert an image to JPG?
Drop the image on this page or tap Upload images. It is converted to JPG straight away; adjust the quality if you like, then tap Download JPG.
How do I change a JFIF file to JPG?
Upload the JFIF file here and download the result. JFIF is the same JPEG format, so nothing is lost; the file simply gets the .jpg extension apps expect.
Can I convert HEIC to JPG here?
Yes, when your browser can open HEIC photos, as Safari on Mac and iPhone does. Chrome, Edge and Firefox cannot decode HEIC yet, and the page tells you when that happens.
What JPG quality should I choose?
Use 90 or more for printing, about 80 for sharing and around 70 when the file has to be small, such as an email attachment. The size of each result updates as you move the slider.
What happens to transparent backgrounds?
JPG cannot store transparency, so transparent areas are filled with the background color you choose: white, black, cream or any custom color.
Is converting to JPG free and private?
Yes. It runs in your browser with no sign-up and no watermark, and your images stay on your device unless you choose Send to.
What is the difference between JPG and JPEG?
None. They are two extensions for the same format; early Windows only allowed three letters, so .jpg became common. Every app that opens .jpeg also opens .jpg.
How do I make a JPG file smaller?
Lower the quality to around 75 and set Maximum size to 2K or 1080 px. Shrinking the dimensions usually saves far more than lowering quality, and the list shows the new size before you download.
Why does my PNG get bigger when I convert it to JPG?
Small graphics with few colors are stored very efficiently as PNG. JPG is built for photos, so for simple graphics the PNG can be the smaller file. In that case keep the PNG.
Can I convert a screenshot to JPG?
Yes. Paste the screenshot straight onto the page with Ctrl or Cmd + V and download the JPG. Use quality 90 or more so small text stays sharp.
Can I convert many images to JPG at once?
Yes, up to 30 per batch. They convert one after another while you watch, and Download all saves them together in a single ZIP file.

Before and after: what changes
Turning an image into a JPG trades a little invisible detail for a file that is small and opens everywhere. The quality slider decides how much detail you keep, and the new size is shown for every file before you download.
- What changes
- The format becomes JPEG with the .jpg extension, and the size depends on the quality you pick. A PNG screenshot of 2 MB often becomes 300 KB at quality 85. Transparent areas are filled with the background color you choose.
- What stays the same
- Dimensions, framing and color, unless you lower Maximum size. Photos from phones are turned the right way up first, so the JPG is upright on every website, even the ones that ignore rotation tags.
- What to look at when you compare
- Drag the divider over fine texture, clear skies and small text. At 85 and above the two sides look identical to most eyes; below about 60, soft blocks and halos around edges start to appear.
Images that make great JPGs, and ones better kept as PNG
Works well
- Photos of people, places, food and products, where JPG keeps them looking natural at a fraction of the size.
- WebP, AVIF and JFIF downloads that a form, printer or older program refuses to accept.
- Big PNG exports and screenshots full of photo content that are too heavy to email or upload.
Avoid
- Logos, icons and stickers that must stay transparent: JPG has no transparency, so keep them as PNG.
- Diagrams and screenshots made mostly of text and flat color, which stay crisper and are often smaller as PNG.
- Images you plan to edit and save many times, because every JPG save loses a little more detail.
Step by step
- Add the imagesDrop them on the page, paste with Ctrl or Cmd + V, press Upload images or choose from your library. WebP, PNG, JFIF, AVIF, GIF, BMP and HEIC files are accepted, up to 30 at once.
- Choose a presetHigh quality suits printing, Balanced suits everyday sharing, Small for email shrinks large photos to 2048 pixels, and Social media saves 1080-pixel images ready for posting.
- Fine-tuneMove Quality and watch each file's new size update. Pick the background color for transparent images and change Maximum size if you need smaller pictures.
- Save the JPGsDownload a single JPG from its row, or Download all for a ZIP of every converted image. Files keep their names with the .jpg extension.
What the JPG settings actually do
- Quality
- JPEG splits the picture into 8 × 8 pixel blocks and stores fewer fine details per block at lower quality. Between 80 and 92 the savings are big and the loss is hard to see, which is why the presets sit there.
- Background color
- A JPG cannot be transparent, so transparent pixels are first painted with your chosen color and the image is drawn on top. White suits documents, black suits dark slides, and a custom color matches a website.
- Maximum size
- Original keeps the full resolution. 4K, 2K and 1080 px shrink the longest side when it is larger, which cuts the file size far more than lowering quality and keeps photos sharp on screens.
- HEIC and JFIF
- JFIF is plain JPEG with an old extension and converts without loss. HEIC needs a decoder from the browser itself; Safari has one, while Chrome, Edge and Firefox do not yet.
