How to convert images
- Add your images. Drag them onto the box above or tap it to choose files. You can mix formats in one batch, for example a few PNG screenshots and some WebP files saved from websites.
- Choose the format under Convert to: JPG, PNG or WebP. A short note under the buttons explains what to expect from each.
- Set the quality if you picked JPG or WebP. The default of 92% suits most uses; move it down for smaller files.
- Press Convert. A progress bar shows which image is being worked on.
- Download each converted image, or press Download all to get a ZIP. The list shows each file's size before and after.
Features
- Six input formats: JPG, PNG, WebP, AVIF, BMP and GIF.
- Three output formats: JPG, PNG and WebP.
- Batch conversion with a single ZIP download.
- Adjustable quality from 40% to 100% for JPG and WebP.
- File size before and after for every image, so you can see what the new format did.
- Same pixel dimensions as the original, with nothing cropped or stretched.
- Transparent areas become white when converting to JPG, so logos and cut-outs don't turn black.
Choosing the right format
Each of the three formats is good at something different, and the right choice depends on where the image is going.
JPG is the safe choice for photographs you want to send, print or upload to a form. Every device, app and website accepts it, and it keeps photo file sizes small. It has no transparency.
PNG is lossless, so it never adds compression artefacts. It suits screenshots, diagrams, logos and images with text, and it supports transparency. Photos saved as PNG are much larger than the same photo as JPG.
WebP was designed for websites. It usually produces smaller files than JPG at similar visual quality, and it supports transparency like PNG. All current major browsers display it, but some older desktop programs and upload forms still don't accept it.
If you already know the exact conversion you need, the dedicated pages explain the details for each one: PNG to JPG, WebP to JPG and JPG to WebP.
Why use Fileora's image converter
Converting an image doesn't require sending it to someone else's computer. Fileora uses the image engine already built into your browser, so your photos are read and saved on your own device. Nothing is uploaded, nothing is stored, and there's no daily limit on how many files you convert.
The tool is free, doesn't add a watermark and doesn't ask for an email address or account. It works on phones and tablets as well as computers, which is handy when a website rejects a photo straight from your camera roll because of its format.
A new format often solves one problem and reveals another, usually file size. If the converted image is still too large for a form, run it through the image compressor to bring it under a limit such as 100KB.
Good to know
Converting between formats can't add detail that isn't there. A small, blurry JPG converted to PNG is still small and blurry, just in a bigger file. Re-encoding also means camera information such as the date and location stored inside a photo is not copied to the new file, which is often useful before sharing a picture publicly.
