Image Converter
Convert images between JPG, PNG, WebP and AVIF. Drag in many files at once and download them separately or in a ZIP.
Quick answer: To convert an image, add your files, choose JPG, PNG, WebP or AVIF (AVIF is offered only where your browser can create it) and press Convert. Transparent areas are kept for PNG and WebP and filled with a colour you pick for JPG. Everything runs in your browser, so your files are not uploaded.

How do you use the Image Converter?
- Add your images. Drag in, choose or paste the images you want to convert.
- Choose the format and quality. Pick JPG, PNG, WebP or AVIF and set the quality for formats that discard detail.
- Press Convert. Download each converted file or all of them in one ZIP.
How to convert images
- Add your images by dragging, selecting or pasting them.
- Pick the format in “Convert to”.
- Adjust quality if the format is lossy, and choose a background colour if you are saving to JPG.
- Press Convert and download the files individually or as a ZIP.
You can open JPG/JPEG, PNG, WebP, AVIF, GIF, BMP and SVG files, as far as your browser can read them, and save them as JPG, PNG, WebP or AVIF.
Choosing the right format
| Format | Best for | Transparency | Compression |
|---|---|---|---|
| JPG | Photos you want to share anywhere | No | Lossy |
| PNG | Logos, screenshots, graphics you will edit | Yes | Lossless |
| WebP | Modern websites and apps | Yes | Lossy or lossless |
| AVIF | Smallest files where supported | Yes | Lossy |
See MDN's guide to image file types for the full technical detail behind each format.
Transparent backgrounds
PNG, WebP and AVIF can store transparency, while JPG cannot. When you convert a transparent image to JPG, the transparent areas are filled with a background colour, white by default, and you can pick another to match your page or document.
Why AVIF may be missing
The tool can only create a format that your browser can encode. AVIF and WebP are checked on your device, and an option only appears when it works. Current versions of Chrome and Edge can create AVIF; if you do not see it, choose WebP instead.
The five conversions people ask for, and what each one changes
Separate pages used to exist for each of these; they are all handled here. Pick the target format in the tool and add your files.
| Conversion | Why people do it | Transparency | File size | Quality |
|---|---|---|---|---|
| JPG to PNG | Editing, logos and graphics you will re-save many times | None is added: a JPG has none, so the PNG is fully opaque | Usually several times larger | Lossless from now on, but it cannot restore detail JPG already discarded |
| PNG to JPG | Smaller photos and screenshots for email, forms and the web | Lost: see-through areas are filled with a colour you pick (white by default) | Usually a large saving for photos | Lossy: quality starts at 90, 75–85 saves more with little visible change |
| WebP to PNG | Opening a saved WebP in an editor or upload form that rejects it | Kept | Often much larger than the lossy WebP | Preserves the decoded pixels exactly |
| WebP to JPG | The safest format to share, print or email | Lost: filled with a colour you pick | Somewhat larger than WebP, far smaller than PNG | Lossy to lossy adds a little extra loss, so keep quality at 90 or above |
| PNG or JPG to WebP | Faster websites | Kept (PNG transparency stays) | Google reports lossy WebP is typically 25–34% smaller than comparable JPGs, and lossless WebP about 26% smaller than PNGs | 75–90 usually looks the same as the original |
Why you end up with a WebP you never asked for: many sites serve WebP because it loads faster, so “Save image as” often gives a file that older editors, print services and upload forms reject. Convert it to JPG if the form wants a photo, or PNG if you need to keep a transparent background.
Convert copies, not originals. Each conversion between lossy formats trades a little quality for compatibility, so keep your first file as the master.
Which format for which job
- Sending a photo to someone or uploading it to a form: JPG, because everything opens it.
- Keeping a logo, icon or screenshot crisp, or editing it again: PNG.
- Publishing on your own website: WebP, or AVIF where your browser can create it, for the smallest files.
- Anything that needs a see-through background: PNG, WebP or AVIF, never JPG.
If you are unsure, convert a copy to two formats and compare the sizes in the results list before downloading. web.dev's guide to choosing an image format covers the same decision for a website.
The quality slider
The quality value applies to formats that discard detail (JPG, WebP and AVIF), and it starts at 90. Lower values make smaller files but can show blocky edges and blurred text. Values above 90 rarely look different to the eye while making the file noticeably larger. PNG is lossless, so the slider is not needed when PNG is the target.
Converting in bulk
You can add up to 100 files, each up to 60 MB, and convert them together. A progress popup shows the percentage and lets you cancel, and the results appear with the size of each file. Download them singly, or take them all in one ZIP so a whole folder arrives in one go. Output files keep the original name with the new extension.
Quality, conversions and the limits of converting
Converting does not improve an image. Turning a JPG into a PNG keeps every flaw JPG compression already added and usually makes the file larger, and a lossy conversion adds a little more loss. Keep your originals. If you convert and shrink together, the image compressor sets a maximum file size, and the image resizer changes dimensions. Everything is processed in your browser and animated images are saved as a single still frame.
Frequently Asked Questions (FAQs)
You can open JPG/JPEG, PNG, WebP, AVIF, GIF, BMP and SVG files (as far as your browser can read them) and save them as JPG, PNG, WebP or AVIF.
Use JPG for photos you want to share anywhere, PNG for logos, screenshots and transparency, and WebP or AVIF for the smallest files on modern websites.
AVIF is only offered when your browser can create it. Current versions of Chrome and Edge can; if yours cannot, choose WebP instead.
PNG, WebP and AVIF keep transparency. JPG cannot, so transparent areas are filled with a background colour that you can pick (white by default).
Yes. Drop up to 100 images in, run them in one go and then download each file separately or all of them together in a single ZIP file.
No. Everything happens inside your browser, so your photos never leave your device. There is no upload, no account and nothing is stored on our servers.
Add your JPG or PNG files, choose WebP as the target and convert. WebP files are usually 25–35% smaller than JPG or PNG at similar quality.
Yes. Add as many as you like, convert them together in bulk online and download them separately or as one ZIP file.
WebP is the best all-round choice today. Use JPG when you need the widest compatibility and PNG for logos and transparency.
JPG cannot store transparency, so transparent areas are filled with a background colour. It is white by default, and you can pick another colour before converting.
Some older editors, print services and upload forms do not support WebP. Convert to JPG for the widest compatibility, or to PNG if the image has a transparent background you want to keep.
