Guides for common jobs

Resizing and compressing

Image resizer scales to a width, a height or a percentage with the aspect ratio locked, or stretches to exact pixels when a template demands it, and shows before-and-after dimensions and file size. Aspect ratio cropper crops to a chosen ratio — 16:9, 4:5, 1:1, or your own — with a draggable frame and exact pixel output. Compress to KB reduces an image until it fits under a stated file size, by adjusting quality and, if needed, dimensions, and shows the result before you download. Image to WebP converts JPEG and PNG to the smaller modern format with a quality slider and a side-by-side comparison. Image DPI sets the resolution metadata for print without resampling pixels.

Cleaning and privacy

EXIF stripper removes the camera, location and timestamp metadata that photographs carry, and shows you what was there. Image redactor blurs or blacks out regions you draw, and flattens the result so the covered content is really gone rather than hidden in a layer. Transparent PNG background removes a flat or near-flat background colour with a tolerance control.

Converting and stylising

Image to ASCII renders a picture as characters, with width and charset options. Pixel art upscaler enlarges small sprites by integer factors with nearest-neighbour sampling so edges stay crisp. Film grain adds adjustable noise for a photographic look. GIF frame extractor breaks an animation into its individual frames for download. Steganography hides a text message in an image's pixels and reads it back out.

Web assets

Favicon package takes one image and produces every size and format a site needs — ICO, PNGs, Apple touch icon, manifest icons — with the HTML to link them. SVG optimiser strips editor metadata, collapses paths and rounds coordinates, typically halving file size without visible change.

Generating

QR code generator produces codes for URLs, text, Wi-Fi credentials and contact cards at any size, with error correction and colour options, as PNG or SVG. Barcode generator does the same for EAN, UPC, Code 128 and the other common symbologies. ASCII art renders text in large letterforms in a choice of figlet-style fonts.

Why nothing is uploaded

Photos often contain people, locations and documents. Every tool here processes the file on your device with the Canvas and File APIs, and the file never leaves your browser.
