Protect transparency
Transparent pixels survive only when the output format supports them. Use PNG or WebP for logos, overlays and cut-out product images.
Avoid repeated conversion
Every new lossy export can discard more visual data. Keep a high-quality original and generate delivery copies from that source.

Common conversion mistakes
- • Converting a transparent logo to JPG without selecting a suitable background.
- • Assuming every conversion automatically produces a smaller file.

- • Replacing the only original with a compressed delivery copy.
Which image format should you choose?
JPG
Best for photographs, marketplace listings and systems that require broad compatibility. It does not support transparency.
PNG
Best for transparency, screenshots, diagrams, logos and sharp interface graphics. Photograph files can be large.
WebP

Frequently asked questions
Which image format is best for websites?
WebP is a strong modern default for many website photographs and graphics. JPG remains widely compatible, while PNG is preferable when transparency or lossless sharp edges are essential.
Can this tool convert AVIF images?
AVIF input works when your browser can decode AVIF. Output is available as JPG, PNG or WebP because those formats have broad browser canvas support.
Does image conversion reduce quality?
PNG output is lossless, while JPG and WebP use adjustable quality. Converting repeatedly between lossy formats can reduce detail, so always work from the best original available.
How do I preserve transparency?
Choose PNG or WebP output. JPG does not support transparency, so transparent pixels are replaced with the background colour selected in the tool.
Can I resize while converting?
Yes. Enable resizing and enter a target width. The height is calculated proportionally to avoid stretching the image.
Why can the converted file be larger?
File size depends on dimensions, format, quality, transparency and image complexity. Converting a compact JPG to lossless PNG can create a larger output.
Are my images uploaded to FormatForge?
No. This converter performs image decoding, drawing and export locally in your browser during the normal workflow.
Should logos be converted to JPG?
Usually not. JPG removes transparency and can introduce visible artifacts around text and sharp edges. SVG, PNG or WebP are generally better choices for logos.
Is WebP better than JPG?
WebP often provides smaller files at comparable quality and can support transparency. JPG remains useful when maximum compatibility with older systems is required.
Can I use converted images for online forms?
Yes, provided you match the portal's accepted format, maximum file size and required dimensions. Inspect text and identification details before submitting.
