Free Online Image Tools — No Upload Needed

Image editing and conversion come up constantly in web development, design and content work — but most online tools upload your images to a remote server to process them. Every tool in this collection processes your images locally in your browser, using the Canvas API, FileReader and WebAssembly libraries. Your files never leave your device, there is no sign-up, and nothing is watermarked.

Edit, Crop and Resize Images

The Image Editor is a full browser-based editor: resize to exact pixels or social-media presets, crop with an aspect-ratio lock, rotate and flip, add text overlays and watermarks, fill a background color, compress with quality control and convert between formats. The Image Compressor is built for batches — drop several PNG, JPEG, WebP or AVIF files at once, compress or convert them in parallel, and compare before and after with a live split slider before you download.

Remove Backgrounds and Relight Photos

The Image Background Remover makes a transparent PNG or WebP locally: remove a white background, pick a color to remove, or use a magic-wand selection with tolerance and edge feather, with zoom and pan for precise work. Relight Photo adds draggable studio, neon, sunset and product lights to an existing photo, lets you adjust ambient brightness and shadows, and exports PNG, JPEG or WebP with a before/after preview.

Convert Between Formats

Image to SVG traces PNG, JPEG and WebP images into scalable vector paths with adjustable color and detail settings. SVG to PNG rasterizes vectors at any scale or pixel size for app icons, email headers and retina displays. Image to Base64 turns any image into a Data URI, an HTML img tag or a CSS background-image ready to embed without an extra file request.

Text, Color and Social Images

The Image to Text Converter uses Tesseract.js — a WebAssembly build of the Tesseract OCR engine — to extract editable text from photos, screenshots and scans in 16 languages, with no cloud API key. The Image Color Palette Extractor pulls the dominant colors out of any image. The OG Image Generator creates 1200×630 Open Graph images, which noticeably improve click-through when a link is shared on Twitter, LinkedIn or Slack, and the Favicon Generator produces the complete set of favicon assets — eight PNG sizes, a multi-size favicon.ico, the Apple Touch Icon, Android Chrome icons and site.webmanifest — in one ZIP. Code Screenshot turns a snippet into a shareable image with themed window frames and gradient backgrounds.

Why Use These Image Tools?

Because all processing uses the browser's Canvas API and WebAssembly, there is no upload time, no server queue and no file-size limit set by a remote service. That matters for client photos, proprietary product images, medical scans and personal documents that should never leave your machine. Open a tool, drop your file, adjust the settings and download — the whole workflow happens in one browser tab, and the tools keep working offline once the page has loaded.
