About the Image Converter
This converter changes an image from one file format to another — for example JPG to WebP, or PNG to TIFF — without needing to install any software. It supports JPG, PNG, WebP, BMP and TIFF, and lets you set the output quality for the formats that use lossy compression.
WebP is usually the biggest win for websites: it is typically 25–35% smaller than an equivalent JPG at the same visual quality. PNG is the right choice when you need lossless output or transparency, and TIFF suits print workflows that need an uncompressed master file.
How to use it
- 1Drag an image onto the drop area, or click to browse for one. PNG, JPG, WebP and TIFF are accepted, up to 10 MB.
- 2Check the image details shown — dimensions, format, colour channels and whether it has an alpha channel — to confirm you picked the right file.
- 3Choose the output format. Adjust the quality slider if you selected JPG, WebP or TIFF; higher values mean a larger file with fewer compression artefacts.
- 4Convert, then download the result. The converted image is generated fresh from your upload and is never stored on our servers.
When you would use it
- Preparing images for a website, where switching JPG or PNG to WebP cuts page weight without a visible change.
- Converting a screenshot to PNG, because JPG compression smears the hard edges of text and interface elements.
- Producing a TIFF master for a print workflow, or a BMP for older software that still expects one.
How it works, and what it does not do
Conversion runs on our server using the libvips image library, which is why the upload leaves your browser. The library decodes the source, re-encodes it in the format you chose at the quality you set, and streams the result straight back. The file is held in memory for the length of the request and is never written to disk.
What it deliberately does not do is edit. It will not resize, crop, rotate, adjust colour or add a watermark, and it will not touch an animated GIF or an SVG — it is a format converter, not an image editor. If you need a different size, convert first and resize in a tool built for that.
Frequently asked questions
Will converting reduce my image quality?
Only if you choose a lossy format with a low quality setting. Converting to PNG is lossless, and raising the quality slider to 90–100 keeps JPG and WebP artefacts negligible for most uses. Note that repeatedly re-saving as JPG compounds artefacts, so work from the highest-quality copy you have.
Are my images uploaded to a server?
Yes — conversion runs on our server, not in your browser, because the image processing library needs to run outside the page. The file is held in memory only for the duration of the conversion and is never written to disk or kept afterwards.
Does converting change the image dimensions?
No. The converter changes the container format and compression only; width, height and aspect ratio are preserved exactly.
Why is my converted file sometimes larger?
Format efficiency varies by image content. A flat graphic with few colours compresses far better as PNG, while a photograph usually compresses better as WebP or JPG. Converting a photo from WebP to PNG, for example, will often increase the file size considerably.
What is the largest image I can convert?
10 MB per file. The limit is enforced before the upload body is read, so an oversized image is rejected outright rather than buffered in memory first.
What happens to transparency when I convert to JPG?
It is lost, because JPG has no alpha channel at all — transparent areas have to be filled with a solid colour. That is a property of the format rather than of this tool. Use PNG or WebP if you need to keep transparency.
