AT USE's image converter tools cover over 50 format pairs — JPG to PNG, PNG to WEBP, WEBP to JPG, HEIC to JPG, PDF to image formats, and more. All conversions run server-side using ImageMagick, so the output is accurate and color-correct. Transparency is handled correctly. Color profiles are preserved. Metadata survives the conversion.

Who needs these tools? Web developers preparing images for production. Designers converting exports to delivery formats. Content creators who received an iPhone photo in HEIC and need a JPG right now. Marketers converting product images to WEBP for faster page loads. Anyone who needs a specific format immediately without installing software or creating an account.

Choosing the right format

For web: WEBP gives the best compression-to-quality ratio for photos on modern browsers. AVIF compresses further but has less universal compatibility as of 2026. JPG is the safe default when you don't control the viewer's environment. PNG is right for logos, screenshots, and anything with transparency or sharp text on a solid background — JPG compression creates visible artifacts on hard edges.

For email and social media: JPG is still the standard. Most platforms recompress uploads anyway, so export at 80–90% quality and move on.

For print: TIFF preserves layers, color profiles, and lossless detail. Send TIFF to printers, not JPG. For browser favicons, ICO format is required. AT USE's ICO converter produces multi-resolution ICO files natively.

Files up to 20 MB are supported. Files uploaded for conversion are processed server-side and deleted automatically — never stored persistently or analyzed.

Frequently asked questions

What is the difference between WEBP and AVIF?

Both are modern compressed formats designed for the web. WEBP (developed by Google) produces file sizes 25–35% smaller than JPG at equivalent quality and is supported by all major browsers. AVIF achieves even smaller file sizes — roughly 50% smaller than JPG — but encoding is slower and browser support, while improving, is not fully universal. For most production use, WEBP is the practical choice. AVIF is worth using when your audience is on modern browsers and every byte of file size matters.

When should I use PNG instead of JPG?

PNG is the right format for images with transparency, logos, screenshots, text overlaid on a solid background, or graphics with sharp edges and flat colors. JPG uses lossy compression that creates visible artifacts around hard edges and blurs fine text. PNG uses lossless compression that preserves detail exactly — at the cost of larger file sizes. For photographs with no transparency where file size matters, JPG or WEBP is more appropriate.

Which image formats support transparent backgrounds?

PNG, WEBP, AVIF, and GIF all support transparency. JPG does not — transparent areas become white or black when saved as JPG. TIFF can store alpha channels but most web applications do not render TIFF transparency. If you convert a PNG with transparency to WEBP, the transparency is preserved. If you convert to JPG, it is lost. Always check the output format when transparency is part of the design.

What format should I use for web images?

WEBP for almost everything: photos, illustrations, UI screenshots. It is supported by all modern browsers, loads faster than JPG at equivalent quality, and supports transparency unlike JPG. For cases requiring older browser support, JPG (photos) and PNG (graphics with transparency) are the safe fallback. Use AVIF if your analytics confirm your audience is on very recent browsers and maximum compression is a priority.

Is there a file size limit for image converters on AT USE?

The upload limit is 20 MB per file. This covers most working files — web images, social assets, print-ready PNGs, and HEIC photos from a recent smartphone. Very large files such as raw 600 DPI scans can exceed the limit; resize or reduce resolution before converting in those cases.
