Convert an image and control the quality
Sometimes an image is simply in the wrong format: a HEIC photo that will not open, a heavy PNG that should be a JPG, or a JPG that would be lighter as WebP. This converter reads almost any image format your browser can open, plus HEIC and TIFF through built-in decoders, and saves it as JPG, PNG or WebP.
Unlike the one-click converter pages, this tool gives you a quality slider for JPG and WebP output, from 10 to 100 percent. It shows the original size and the converted size, which makes it easy to experiment until you find the smallest file that still looks right.
How to convert an image format
Step 1: Drop one image
JPG, PNG, WebP, GIF, BMP, AVIF, TIFF, HEIC and SVG are accepted.
Step 2: Choose JPEG, PNG or WebP
WebP is selected by default for small, modern files.
Step 3: Set the quality
For JPEG and WebP, drag the slider; 90 percent is the default. PNG is always lossless.
Step 4: Convert and download
Compare the sizes shown, then download the converted image.
What the converter offers
Three output formats
JPEG for photos, PNG for lossless graphics, WebP for small web images.
Quality from 10 to 100
Fine control over the size and quality trade-off for JPEG and WebP.
Wide input support
HEIC and TIFF are decoded in the browser; SVG is rendered at high resolution.
White background for JPEG
Transparent areas become white instead of black when saving JPEG.
Common format changes
iPhone HEIC to JPG. Make a photo readable on Windows, Android and upload forms.
PNG to WebP for websites. Keep transparency with a fraction of the file size.
Screenshot to JPG. Shrink a large capture for email when sharp text is not critical.
Anything to PNG. Get a lossless copy for editing in design tools.
Picking the right output format
JPEG is the universal choice for photos and opens everywhere. PNG is lossless and keeps transparency, ideal for logos, icons and screenshots, but it is large for photographs. WebP handles both photos and graphics, supports transparency and is usually the smallest, which makes it the best choice for websites.
If the image is headed for print, email or older software, choose JPEG. If it will live on a website, try WebP first and compare the sizes.
- Photos for sharing: JPEG at 80 to 90 percent.
- Web images: WebP at 75 to 90 percent.
- Graphics and editing masters: PNG.
What is and is not preserved
Dimensions and orientation are preserved. Metadata such as EXIF and GPS is not copied into the new file. Animated GIFs and animated WebP files are converted using their first frame only.
Converting between lossy formats adds a small amount of compression each time, so convert from the original whenever possible. Safari can display WebP but cannot always create it; use Chrome, Edge or Firefox if WebP output fails.
Tips for format conversion
- Start at 85 to 90 percent quality and lower it only while the image still looks right.
- Use PNG for anything with sharp text or thin lines.
- Convert many files at once with the bulk image converter.
- Check the before and after sizes; if the new file is larger, a different format may suit the image better.
Image format converter FAQ
Which formats can I convert to?
JPEG, PNG and WebP, the three formats every modern browser can both read and create.
Can I convert HEIC files?
Yes. HEIC photos are decoded in the browser and can be saved as JPEG, PNG or WebP.
Does PNG have a quality setting?
No. PNG is lossless, so the slider only applies to JPEG and WebP.
What happens to transparency?
PNG and WebP keep it. JPEG has no transparency, so those areas are filled with white.
Why is the converted file larger?
Converting a compressed format to a lossless one, such as JPG to PNG, increases the size. Choose WebP or JPEG for smaller files.
Is my image uploaded?
No. The conversion happens entirely in your browser.
