Image manipulation tools

Convert, shrink and edit images without installing software

Most image jobs are small and repetitive: a screenshot saved as PNG that needs to be a JPG for an upload form, a phone photo in HEIC that Windows will not open, a logo that has to become an ICO favicon. The tools here cover those format swaps in every direction between PNG, JPG, WebP, AVIF, GIF, BMP, ICO and HEIC.

Beyond conversion, the category includes editing and inspection tools. You can resize, crop, rotate, blur, pixelate, watermark and adjust brightness or contrast, pull a color palette out of a picture, read the EXIF metadata a camera embedded, or remove a background. Web designers, bloggers, store owners and anyone preparing files for email or a CMS tend to use them.

The tools chain naturally. A typical run is to crop a photo, resize it to the width your page needs, compress it, and convert it to WebP or AVIF for a smaller download. Each step is its own page, so you can stop wherever the file is good enough.

Common questions

Which image format should I choose for a website?

WebP or AVIF usually give the smallest files for photos at similar quality, while PNG is better for screenshots and graphics with sharp edges or transparency. JPG remains the safest choice when the file must open everywhere, including older software.

Does converting an image reduce its quality?

Converting to a lossy format such as JPG, WebP or AVIF discards some detail, and repeating the conversion discards more. Converting to PNG or BMP keeps the pixels exactly as they are, though the file may grow considerably.

Why does my phone photo not open on some computers?

Recent iPhones save photos as HEIC, a compact format that many Windows programs and web forms cannot read. Converting the file to JPG or PNG with the HEIC tools gives you an image that opens almost anywhere.
