Files never leave your device. Check the network tab if you like.
How it works
Add images by dragging them onto the page or choosing files. Each one is decoded and re-encoded by your browser, so the conversion starts immediately and runs as fast as your device allows. Change the format, quality or size and press Apply to redo the whole batch, then download files one by one or as a single ZIP.
Which format should you pick?
JPG is the safe choice for photos going anywhere: every device, app and website opens it. PNG keeps transparency and sharp edges, so use it for logos, screenshots and graphics with text. WebP is 25–35% smaller than JPG at the same quality and is supported by every modern browser, but some older apps and government upload forms still reject it.
| Format | Best for | Transparency | Typical size |
|---|---|---|---|
| JPG | Photos, email, forms, printing | No | Small |
| PNG | Logos, screenshots, text | Yes | Large for photos |
| WebP | Websites, app assets | Yes | Smallest |
Quality settings that actually matter
JPG and WebP quality is a 1–100 scale, but it is not linear. Between 100 and 85 the file shrinks a lot and you cannot see the difference. Between 85 and 70 the file keeps shrinking and photos still look clean on screens. Below 60 you start to see blocky artifacts in skies and skin. For anything you will print, stay at 90 or above; for a website, 70–80 is the usual sweet spot.
Resizing saves far more than quality does. A 12-megapixel phone photo is 4000 pixels wide; a screen shows at most 2000 and a chat app thumbnail a few hundred. Setting the longest side to 2048 typically cuts the file by 70% before any quality change.
Why nothing is uploaded
Most online converters send your photos to a server, process them there and keep a copy for a while. This page uses the image decoder built into your browser and, for iPhone HEIC files, a small WebAssembly decoder that downloads once. Your originals and the results stay on your device, which is why there is no file limit, no queue and no account.
Re-encoding also strips EXIF metadata such as GPS location and camera serial number, which is usually what you want before posting a photo publicly.
Frequently asked questions
- Is there a file size or count limit?
- Up to 50 files per batch and 60 MB per file, limited only by your device's memory. Very large images may be slow on older phones.
- Does converting remove the location data from my photos?
- Yes. The output contains pixels only; EXIF data including GPS, date and camera model is not copied.
- Why is my PNG larger than the original JPG?
- PNG is lossless, so it cannot compress photographic detail the way JPG does. Use PNG for graphics and JPG or WebP for photos.
- Does it work on my phone?
- Yes, in Safari and Chrome on iOS and Android. Choosing files opens your photo library.
- Can it convert PDFs or videos?
- No. This tool is for still images only.
