Which image formats can I convert to?

You can convert to and from JPEG, PNG, WebP, AVIF, GIF, TIFF and BMP. All common web and print formats are supported.

Will converting PNG to JPEG lose quality?

PNG to JPEG conversion uses lossy compression. You can adjust the quality level. For transparent images, JPEG does not support transparency — use PNG or WebP instead.

What is the best format for web images?

WebP offers the best compression ratio with excellent quality. JPEG is best for photos, PNG for graphics requiring transparency.

Can I convert JPEG to PNG to get transparency?

The JPEG format does not have transparency data to recover. For true transparency, start with a PNG or WebP source.

Is there a file size limit?

Files up to 50 MB are supported on the free tool.

How to convert an image online for free?

Converting an image changes its file format (JPEG, PNG, WebP, GIF, BMP, AVIF) with no visible quality loss. FileSwiftly handles your image conversion directly in the browser — no installation, no absurd size limits.

Which image format should you choose?

JPEG: ideal for photos, excellent size/quality ratio. PNG: perfect for logos and screenshots with transparency. WebP: the modern web standard — 30% lighter than JPEG at equivalent quality, supported by all modern browsers. AVIF: the future of web image formats, even better than WebP but less compatible. GIF: simple animations, but limited to 256 colours.

Convert HEIC to JPG (iPhone)

Photos taken with an iPhone are saved in HEIC format — poorly compatible with Windows and most software. Our converter transforms your HEIC files to JPEG or PNG in seconds, preserving EXIF metadata (date, location, device).

Batch conversion with FileSwiftly Pro

The free plan converts one image at a time. FileSwiftly Pro enables batch conversion of up to 50 images simultaneously, with WebP and AVIF export, and REST API access to automate your workflows.

FAQ

Does conversion change image dimensions?

Dimensions (width × height) remain identical. Only the format and file weight change. To resize, use our Resize tool.

Is WebP supported everywhere?

Yes. Since 2020, all major browsers (Chrome, Firefox, Safari, Edge) support WebP natively. It's the recommended format for the web.
