JPEG
Best for photos and maximum compatibility. JPEG keeps files small but does not support transparency.

Quality affects lossy formats. PNG uses color precision because it is lossless at the pixel level.

Format guide
Which image format should you choose?
The best format depends on transparency, compatibility, and whether you want a smaller file. Convert images in your browser and preview the output before downloading.
PNG
Best for logos, screenshots, and transparent graphics. PNG preserves sharp edges and alpha channels.
WebP
A strong default for websites and apps. WebP supports transparency and usually delivers a smaller file than JPEG.
AVIF
Best when modern browser support is acceptable and file size matters most. AVIF can preserve quality at very small sizes.
Convert an image in three steps
Kein Konto und kein Upload erforderlich. Your browser decodes the source and creates the new file locally.
- 01
Add your images
Drop one or more images, browse for files, or paste an image directly from your clipboard.
- 02
Pick the output format
Choose JPEG, PNG, WebP, or AVIF, then adjust quality when the format supports lossy encoding.
- 03
Preview and download
Start the conversion, compare the result with the original, and download one file or a ZIP archive.
Common image conversion scenarios
Use the converter when a platform, design workflow, or delivery channel expects a different image format.
HEIC photos from iPhone
Convert HEIC or HEIF photos to JPEG for broad compatibility with Windows, websites, email, and older editing tools.
Faster website images
Convert JPEG or PNG assets to WebP or AVIF to reduce transfer size while keeping useful visual quality.
Transparent logos and graphics
Use PNG or transparent WebP when a logo, icon, screenshot, or product cutout needs an alpha channel.
Social and marketplace Uploads
Create a widely supported JPEG copy when a social network, marketplace, or CMS rejects newer formats.
Privacy-first by design
Images are decoded and encoded in your browser with workers and local WASM codecs. The files are not sent to our server, and temporary object URLs are released when they are no longer needed.
FAQ
Image converter FAQ
Are my images uploaded?
No. Conversion runs locally in your browser, so the original images and generated files stay on your device unless you choose to download or share them yourself.
What format is best for photos?
JPEG is the safest choice for maximum compatibility. WebP is a good modern web default, while AVIF is useful when the smallest file matters and the target browser supports it.
Does converting to another format reduce quality?
JPEG, WebP, and AVIF can be lossy, so lower quality settings may remove detail. PNG keeps pixel data lossless, although this page can reduce its color palette for a smaller file.
Can I convert HEIC to JPG?
Yes. HEIC and HEIF files can be decoded in the browser and converted to JPEG, PNG, WebP, or AVIF without uploading the source image.
Can I convert multiple images at once?
Yes. Add multiple images, select one output format, and download the completed files individually or together as a ZIP archive.
When should I use AVIF?
Choose AVIF for modern websites and apps where small file size is important. Use WebP or JPEG when you need broader support across older software and devices.
