Image Format Guide
JPG / JPEG
Best for photographs and complex images with many colors. Uses lossy compression for small file sizes. No transparency support. The most widely used format on the web.
PNG
Best for graphics, logos, screenshots, and images with text. Supports transparency (alpha channel). Lossless compression means larger files but no quality loss.
WebP
Google's modern format. 25-35% smaller than JPG at equivalent quality. Supports both lossy and lossless compression plus transparency. Ideal for web performance.
BMP
Uncompressed bitmap format. Very large files but zero quality loss. Used in specific applications like Windows system graphics and some legacy software.
When to Convert Formats
Converting to WebP can reduce your website's image payload by 25-35% with no visible quality loss — a quick win for page speed and SEO. If your CMS or CDN supports WebP, it should be your default web format.
Converting to PNG is essential when you need transparency (logos on colored backgrounds, product images, overlays). JPG doesn't support transparent pixels, so converting from JPG to PNG gives you a solid background that you can then edit.
Converting to JPG makes sense when you need maximum compatibility — every device, browser, and platform supports JPG. It's also the best choice for email attachments since the files are smaller than PNG.
Detailed Format Comparison Guide
| Format | Compression | Transparency | Animation | Browser Support | Best For | File Size |
|---|---|---|---|---|---|---|
| JPG | Lossy | No | No | Universal | Photos, gradients | Small |
| PNG | Lossless | Yes (alpha) | No | Universal | Logos, icons, text | Medium-Large |
| WebP | Both | Yes (alpha) | Yes | All modern | Web performance | Smallest |
| BMP | None | Limited | No | Universal | Legacy systems | Very Large |
| GIF | Lossless | Yes (1-bit) | Yes | Universal | Simple animations | Medium |
| AVIF | Both | Yes (alpha) | Yes | Growing | Next-gen web images | Smallest |
Browser support reflects current state as of 2026. AVIF is supported in Chrome, Firefox, and Safari but may not work in older browsers. For maximum compatibility, use JPG or PNG. For best compression with modern browser support, use WebP with our compressor.
Format Selection Flowchart
Not sure which format to convert to? Walk through these questions to find the best match for your use case.
Need transparency?
If your image requires a transparent background (logos, overlays, product cutouts), choose PNG for maximum compatibility or WebP for smaller file sizes. JPG and BMP do not support transparency and will flatten transparent areas to a solid background.
Working with a photograph?
Photographs and images with smooth color gradients compress best as JPG or WebP. JPG is universally supported and produces excellent results at 80% quality. WebP produces files 25-35% smaller than JPG at equivalent visual quality — ideal if your target platform supports it.
Need the smallest possible file?
Choose WebP. It consistently produces the smallest files for both photographic and graphic content. For even smaller files on supported browsers, AVIF is emerging as the next-generation option. After converting, you can further reduce size with our image compressor.
Need maximum compatibility?
Choose JPG. Every browser, email client, operating system, and image viewer supports JPG. It is the safest choice when you do not control the viewing environment — email newsletters, downloadable resources, and documents where the recipient's software is unknown.
Need pixel-perfect graphics?
Choose PNG. Its lossless compression preserves every pixel exactly as intended — critical for UI elements, diagrams, screenshots, and images containing text. PNG files are larger than JPG, but the quality trade-off is worth it when sharpness and accuracy matter. You can also resize your PNG to reduce its dimensions and file size.
Frequently Asked Questions
Does converting formats lose quality?
Converting to a lossy format (JPG) will lose some quality. Converting to lossless formats (PNG, BMP) preserves quality perfectly. Converting from JPG to PNG won't restore lost quality — it just prevents further loss.
Will I lose transparency when converting?
Converting to JPG or BMP will flatten transparency to a white background, since these formats don't support alpha channels. PNG and WebP both preserve transparency.
Are my images uploaded?
No. All conversion happens in your browser using the Canvas API. Nothing is sent to any server — your images stay completely private.
