Convert Image Formats Online
Convert images between JPG, JPEG, PNG, WebP, and AVIF to meet compatibility and quality requirements across websites, apps, marketplaces, and social channels. Batch conversion helps speed up repetitive workflows for teams handling multiple assets.
Conversion happens in your browser, which means private local processing and fast output. If you want smaller files after conversion, continue with Compress Images.
JPG is often ideal for photos, PNG works well for graphics with transparency, WebP offers strong web optimization, and AVIF can deliver excellent compression for modern browsers. Choosing the right format helps balance quality, compatibility, and performance.
For best publishing results, convert first to your target format, verify visual quality, and then run a final compression pass. This keeps file size small while preserving detail and color accuracy.
When To Use JPG, JPEG, PNG, WebP, or AVIF
JPG and JPEG refer to the same underlying format — both use lossy compression ideal for photos where small file size matters more than transparency. The difference is purely in the file extension, so choosing between them depends on what your destination system expects. PNG is often better for logos, UI screenshots, and graphics with sharp edges or transparent areas. WebP is widely adopted for modern websites and can provide a strong quality-to-size balance. AVIF may deliver even smaller files, but compatibility should be checked for your target platforms.
If you publish on marketplaces or content systems with strict upload rules, conversion helps avoid rejection caused by unsupported file types. It also helps standardize asset pipelines for teams that receive mixed source files from different designers, devices, or vendors.
A practical workflow is to crop for composition and resize to target dimensions before converting source images to your preferred final format, then inspect key areas like text, gradients, and skin tones. After quality confirmation, compress the converted output to reduce transfer size. This approach improves performance while preserving visual consistency.

Which Image Format Should You Use?
- JPG / JPEG — Best for photos
- JPEG is the universal format for photographs and complex images with many colours. It uses lossy compression to keep file sizes small, making it ideal for sharing and web use. Not suitable for images that require transparency.
- PNG — Best for graphics with transparency
- PNG uses lossless compression and supports full transparency (alpha channel). It is the best choice for logos, illustrations, screenshots, and any image where you need a transparent background or pixel-perfect quality.
- WebP — Best for web performance
- WebP is Google's modern format that produces files 25–35% smaller than JPEG at equivalent quality, and also supports transparency like PNG. It is supported by all modern browsers and is the recommended format for web images.
- AVIF — Best for cutting-edge compression
- AVIF is a next-generation format based on the AV1 video codec. It achieves 50% smaller files than JPEG at the same quality — even better than WebP. Browser support is now widespread, making it a great choice for high-traffic websites.
Frequently Asked Questions
- Can I convert PNG to JPG online for free?
- Yes. Upload your PNG, select JPG as the output format, and download. The conversion happens instantly in your browser with no quality loss beyond what the JPEG format itself introduces.
- Does converting JPG to PNG improve quality?
- No. Converting a JPEG to PNG does not recover any detail lost during the original JPEG compression — it simply wraps the existing pixel data in a lossless container. However, subsequent saves as PNG will not introduce further quality loss.
- How do I convert an image to WebP?
- Upload your JPG or PNG image, select WebP as the output format, and click download. WebP files are typically 25–35% smaller than the equivalent JPEG, making them excellent for web pages.
- Are my images uploaded to a server during conversion?
- No. All format conversion is performed locally in your browser using the HTML5 Canvas API. Your images never leave your device.
- Can I batch convert multiple images at once?
- Yes. Upload up to 10 images at once, choose your target format, and all images are converted simultaneously. Use Download All to save them as a ZIP file.
