What this category is for

Most image work does not actually need a server. Canvas and WebCodecs decode and re-encode the common formats, WebAssembly runs the compression algorithms, and WASM or WebGPU can run the models behind background removal, watermark removal, upscaling and OCR. That premise is what this whole category is built on.

So the photos, ID scans and screenshots you open never leave your device. Background and watermark removal do download open-source model files into the browser first; the model comes from the network, the image you picked does not.

Choosing between these tools

You need a smaller file
Image Compress re-encodes at a chosen quality and keeps the original format by default. If the goal is page load speed, switching the output to WebP or AVIF usually saves over thirty percent against a JPG of the same visual quality.
You need different dimensions, not different quality
Image Resize scales proportionally, Image Crop takes a region by dragging a box, and Image Upscale is for cases where the result still has to look sharp. Scaling down loses little; scaling up has a model invent detail rather than recover real detail.
You need to change the content itself
Remove Background exports a transparent PNG, ID Photo Maker crops to standard sizes and swaps the backdrop after removing the background, Remove Watermark inpaints the region you mark, and Image Editor handles redaction, blur and annotation.
You need information out of an image
OCR extracts text, Color Picker reads HEX / RGB / HSL from any pixel, and EXIF Viewer shows capture settings and location data; and can strip all of it before you export.

Formats and capabilities compared

The output-format trade-off. Picking wrong can multiply the file size, or silently drop the transparency you needed.

FormatTransparencyCompressionBest for
JPGNoLossyPhotographs and broad gradients; the most compatible option
PNGYesLosslessScreenshots, line art, anything needing a transparent background
WebPYesLossy and losslessGeneral web use; clearly smaller than JPG or PNG at equal quality
AVIFYesLossy and losslessSmallest files, but slow to encode and unsupported by older browsers

Limits that apply across this category

Re-encoding stacks losses. Compressing a JPG repeatedly, or converting out and back, discards a little more detail every round; always start from the original, never from the previous output.

Stripping EXIF removes location, device model and capture time together. That is what you want before publishing, but it also means the information is gone for good. Save a copy of the original first if you need it on file.

Background removal, watermark removal, upscaling and OCR depend on model files. The first run downloads tens of megabytes, which is noticeably slow; and sometimes fails; on low-end devices or weak connections.

Frequently asked questions

Do the image tools upload my pictures?
No. Compression, format conversion, background removal, OCR and more all run locally in your browser, so images are never uploaded.
Which image formats are supported?
They convert and process common formats including JPG, PNG, WebP, AVIF, GIF, BMP and SVG.
Are the image tools free?
Yes. Every image tool is free to use without an account and runs directly in your browser.
Do they work in a mobile browser?
Yes. The tools are web-based and work on phones with a modern browser, with processing still done locally.
