Image Converter
Convert images between JPG, PNG, WebP, AVIF, ICO and BMP in one batch, with resizing, a quality slider or a target file size, right in your browser. For websites, WebP is usually the smallest: Google measured it 25–34% smaller than JPEG at the same quality. Drop your images below; nothing is uploaded.

How to convert images
- Choose or drop images. Phone photos are turned upright using their EXIF orientation.
- Pick the output format. WebP for websites, JPG for photos that must open anywhere, PNG for screenshots and logos, ICO for favicons.
- Set quality or a target size, and resize if needed. Results update as you change settings.
- Download each image, or all of them as a ZIP.
Which image format to choose
| Format | Compression | Transparency | Best for | Opens in |
|---|---|---|---|---|
| JPG | Lossy | No | Photos; smallest for camera pictures where WebP is not accepted | Everywhere |
| PNG | Lossless | Yes | Screenshots, logos and text; exact pixels | Everywhere |
| WebP | Lossy or lossless | Yes | Websites: smaller than JPG and PNG with transparency | All current browsers; some older apps cannot open it |
| AVIF | Lossy or lossless | Yes | Websites: often smaller than WebP, slower to encode | Current browsers; encoding only where the browser supports it |
| ICO | Lossless | Yes | favicon.ico and Windows icons (16 to 256 px in one file) | Browsers and Windows |
| BMP | Lossless | No | Old software that needs uncompressed bitmaps | Everywhere; very large files |
In Google's own tests, lossy WebP was 25–34% smaller than JPEG at equal visual quality, and lossless WebP 26% smaller than PNG. Your images will vary: use Compare formats to see the real sizes for your picture.

Quality, size and resizing
- Resize first. A 4000 px phone photo shown 1200 px wide wastes about 90% of its pixels; fitting it to 1200 px cuts the file far more than lowering quality.
- Quality 75–85% looks the same as 100% for most photos at a fraction of the size. Below about 60%, blocks and smudges appear around edges and text.
- Target file size finds the highest quality that fits a limit, useful for forms that reject files over 100 KB or 1 MB.
- PNG, ICO and BMP are lossless: quality does not apply, and only resizing makes them smaller.
Converting does not restore quality. A JPG turned into PNG keeps its JPEG artefacts and just gets bigger. Keep your originals, and convert from the best copy you have.
Metadata and privacy
Converting redraws the pixels, so camera details, dates and GPS location are left behind unless you tick Keep metadata. To clean photos without re-encoding them, use the EXIF Remover; to add copyright that Google Images shows, use the EXIF Editor.
Disclaimer: results depend on your browser's built-in encoders, which differ slightly between Chrome, Safari and Firefox. This tool is provided as is.

Frequently asked questions
How do I convert JPG to PNG or PNG to JPG?
Drop the images on this page, choose PNG or JPG as the output format and download each file or all of them as a ZIP. PNG keeps every pixel exactly and supports transparency but makes photos several times larger; JPG makes photos small but has no transparency, so transparent areas are filled with the background colour you pick (white by default).
Which image format is best for a website?
WebP for most images: Google's study found lossy WebP files 25–34% smaller than JPEG at the same quality and lossless WebP 26% smaller than PNG, and every current browser shows it. Use JPG where a platform does not accept WebP, PNG for screenshots and logos that must stay sharp, and SVG for icons. Compare formats encodes your own image in each format so you can see the smallest.
How do I make an image smaller than 100 KB?
Choose JPG or WebP, tick Target file size and type 100. The converter tries qualities from 100% down and keeps the highest one that fits, usually in 6 to 8 attempts. If even 5% quality is too big, it tells you; then reduce the size with Resize, for example to fit 1200 px wide, which cuts the file far more than quality does.
How do I convert HEIC photos from an iPhone?
Safari on iPhone and Mac can open HEIC, so convert there: drop the photos on this page in Safari and save them as JPG. Chrome and Edge cannot decode HEIC, and the page will say so. To avoid HEIC altogether, set the iPhone's Settings, Camera, Formats to Most Compatible, which saves JPG.
Does converting remove EXIF data and GPS location?
Yes, by default. The converter redraws the pixels, so the new file contains no camera details, date or GPS position. Tick Keep metadata to copy the EXIF and copyright fields from the original into JPG, PNG or WebP output; the orientation is reset because the pixels are already rotated upright. To remove metadata without re-encoding, use the EXIF Remover.
How do I make a favicon.ico?
Choose ICO, keep the sizes 16, 32 and 48 px (add 64 to 256 for Windows shortcuts) and convert a square PNG or SVG logo. The ICO stores each size as a PNG inside one file, which every browser and Windows since Vista read. Put favicon.ico in your site's root folder; Blogger has its own favicon setting under Settings, Basic.
Are my images uploaded?
No. Decoding, resizing and encoding use your browser's built-in image codecs on your device, so images never leave it and the page works offline after one visit. Each image can be up to 80 MB and 60 megapixels; larger photos are scaled down to fit the browser's canvas limit.
