Image Converter
Convert images between JPG, PNG and WebP in bulk, with quality and background options, right in your browser.
Which format should you convert to
Pick JPG for photos you’ll share or upload, PNG for screenshots, logos and anything with transparency, and WebP for images going on a website. That one line covers most cases. The table shows why.
| JPG | PNG | WebP | |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes | Yes |
| Animation | No | No | Yes |
| File size | Small for photos | Large for photos, small for flat graphics | Smallest of the three |
| Accepted by forms and old apps | Almost everywhere | Most places | Less often |
| Best for | Photos, ID scans, upload forms | Screenshots, logos, text, diagrams | Websites and blogs |
On size, Google’s figures (opens in new tab) put lossy WebP at 25 to 34% smaller than comparable JPGs, and lossless WebP at 26% smaller than PNGs. On compatibility, JPG still wins: if a job, exam or bank portal names one format, it is usually JPG or JPEG.
How to use the image converter
- Drop your images into the box above, or click to browse. Mixed formats in one batch are fine.
- Choose Convert to: JPG (the default), PNG or WebP.
- For JPG or WebP, set the Quality slider. It runs from 10% to 100% and starts at 90%. PNG has no slider because it is lossless.
- For JPG, pick a Background colour. JPG can’t store transparency, so see-through areas are filled with it. White is the default.
- Conversion runs on its own. Download each file, or click Download all (ZIP) for the whole batch.
The pixel size stays the same. File names stay the same too; only the extension changes, so logo.png becomes logo.jpg.
What you can convert
The converter accepts any image your browser can open. In current browsers that covers JPG, PNG, WebP, GIF and BMP. AVIF works in Chrome 85, Edge 121, Firefox 93, Safari 16.1 and later, per MDN (opens in new tab). Two formats are better handled by dedicated tools:
- iPhone HEIC photos: only Safari can open HEIC on its own. Use HEIC to JPG, which brings its own decoder and works in every browser.
- SVG graphics: use the SVG converter, which lets you set the output width so the image stays sharp.
- PDF pages: use PDF to JPG to turn each page into an image.
Things that catch people out
Converting to PNG won’t restore lost quality
A JPG has already thrown away detail. Saving it as PNG keeps what’s left, without adding anything back, and the file gets larger. Google’s WebP FAQ (opens in new tab) makes the same point for WebP: converting a lossy source to lossless typically gives a larger file. Convert JPG to PNG only when an app demands PNG.
Transparency disappears in JPG
A PNG logo with a see-through background becomes a logo on a solid box. Set the background colour to match where the image will sit, or pick PNG or WebP to keep the transparency.
Safari saves PNG instead of WebP
Your browser does the encoding, and Safari has not been able to create WebP files from a web page (WebKit bug 226950 (opens in new tab)). When a browser can’t make the requested format, it saves PNG instead (MDN (opens in new tab)). The converter checks what it actually got, so in Safari a WebP request downloads as a .png file, with a note under the result saying so. For a real WebP, use Chrome or Edge on a computer. In Safari, pick JPG or PNG.
Animated GIFs become still images
Only one frame is converted: the frame the file marks as its default, or else the first frame. That’s how browsers draw animated images, as set out in the HTML standard (opens in new tab).
Private by design
Every image is decoded and saved again inside your browser tab. Nothing is sent to a server, so there’s no upload wait, no file count cap and no daily limit. Popular upload-based converters such as FreeConvert and Convertio state that they keep files on their servers for up to 8 hours and 24 hours respectively, as of October 2026. Here, files never leave your device, which matters for ID scans, signatures and family photos.
The output also drops the hidden EXIF data from the original, such as camera details and GPS location.
Limitations
- Three output formats: JPG, PNG and WebP.
- No resizing here. To change dimensions or hit a KB target, use the image resizer after converting.
- Input depends on your browser. If a file shows “could not be read as an image”, your browser can’t open that format.
- EXIF data is not kept, so the date taken and location are removed.
Key facts
- Lossy WebP is 25 to 34% smaller than comparable JPEG at equivalent SSIM quality, and lossless WebP is 26% smaller than PNG. (Google for Developers (opens in new tab))
- JPEG has no alpha channel; PNG is lossless and is the usual fallback for images that need transparency. (MDN (opens in new tab))
- AVIF is supported from Chrome 85, Edge 121, Opera 71, Firefox 93 and Safari 16.1. (MDN (opens in new tab))
- If a browser can’t produce the requested image format, it exports PNG instead. (MDN (opens in new tab))
FAQ
Image Converter FAQs
What is the best free image converter?
The best one converts on your device, keeps quality control in your hands and has no limits. This converter handles JPG, PNG and WebP output, works in bulk with a ZIP download, and never uploads your files. Upload-based tools add a wait and keep copies on their servers for hours.
How do I convert an image to JPG?
Drop the image into the converter above and leave Convert to set to JPG. Set the quality, 90% by default, and pick a background colour if the image has transparent areas. Then download the JPG. You can convert many images at once and save them as a ZIP.
Should I use JPG, PNG or WebP?
Use JPG for photos and upload forms, PNG for screenshots, logos and transparency, and WebP for websites. JPG is the most widely accepted. PNG keeps every pixel but makes large photo files. WebP is the smallest, at 25 to 34% under JPG per Google, but older apps and some forms reject it.
Does converting an image reduce its quality?
Converting to PNG doesn’t, because PNG is lossless. Converting to JPG or WebP re-compresses the image, but at the default 90% quality the change is hard to see. Going from JPG to PNG won’t bring back detail the JPG already lost; it only makes the file bigger.
Can I convert multiple images at once?
Yes. Select or drop as many images as you like, even in different formats. Each one is converted with the same settings, and a Download all (ZIP) button saves them together. There is no file count or daily limit, because the work happens on your own device.
Why did my WebP file come out as PNG?
Your browser can’t create WebP files. Safari has not supported making WebP from a web page, and browsers save PNG when the requested format isn’t available. The converter names the file .png and shows a note under the result, so you know what you got. For WebP, use Chrome or Edge on a computer, or choose JPG in Safari for a smaller file.
Can I convert HEIC or PDF files here?
Use the dedicated tools for those. HEIC to JPG brings its own decoder, so iPhone photos convert in Chrome, Edge and Firefox as well as Safari. PDF to JPG and PDF to PNG turn each PDF page into an image. This converter is for files your browser can open as images, such as JPG, PNG, WebP, GIF, BMP and AVIF.
Are my images uploaded to a server?
No. Images are decoded and saved again inside your browser tab, so they never leave your device. That also means no upload wait and no copy left on a server. The converted file drops the original EXIF data, including any GPS location, which adds a little more privacy.
