Free online image converter, compressor, cropper, and resizer — no upload
ImgShifter (Image shifter) is a free online image converter, image compressor, image cropper, and image resizer that runs entirely in your browser. Convert PNG to JPG, JPG to PNG, WEBP to JPG, JPG to WEBP, PNG to WEBP, AVIF to JPG, AVIF to PNG, JPG to AVIF, PNG to AVIF, WEBP to AVIF, HEIC to JPG, SVG to JPG, SVG to PNG, SVG to WEBP, and PNG/JPG/WEBP to SVG — all without uploading your photo to a server. The browser-based image converter handles the most-searched format pairs people need every day — iPhone HEIC photos to JPG or PNG, modern AVIF and WEBP to legacy formats, lossless PNG to optimised JPG for the web, and SVG rasterisation or vectorisation in either direction — with a live preview and a one-click download for every tool.
Beyond format conversion, ImgShifter is a full no-upload image editor: a free image compressor with a quality slider for JPG, PNG, and WEBP optimisation; a private online image cropper with aspect-ratio presets for 1:1, 4:5, 4:3, 3:2, 16:9, 21:9, and 9:16; a dedicated Instagram image cropper for square posts, portrait posts, Stories, and Reels (1080x1080, 1080x1350, 1080x1920); and a bulk image resizer that processes batches in your browser and bundles the results into a ZIP. All of these run client-side using the Canvas API and on-device WebAssembly — HEIC decoding via the heic-to module, AVIF encoding via @jsquash/avif, JPG and PNG compression via browser-image-compression, and SVG rasterise/vectorise as a pure-JavaScript Canvas pass — so your image never leaves your device.
What makes Imageshifter different from other free online image tools is verifiable privacy. Most online image converters, online image compressors, and online photo croppers still upload your file to a server even when they market themselves as “private” or “secure.” With ImgShifter you can prove the no-upload claim yourself in under a minute: disconnect from the internet, run a PNG to JPG conversion or a batch image resize, and watch it complete with zero outbound network requests. Open the browser’s Network tab and the request count stays at zero during processing. That makes ImgShifter a genuinely private image converter, private image compressor, and offline image editor — not just a marketing label.
A small set of advanced format conversions — TIFF to JPG, TIFF to PNG, and RAW to JPG (Canon CR2, Nikon NEF, Sony ARW, Adobe DNG) — need native decoding libraries that don’t exist in the browser, so they route to the ImgShifter conversion service over an encrypted HTTPS connection. Every server-side tool is clearly labelled in the tool list, and originals are not retained beyond the conversion request. Whether you’re a creator cropping iPhone photos for Instagram, a marketer compressing JPG and WEBP assets for faster page load, a photographer converting HEIC, RAW, or TIFF, or a developer optimising AVIF, WEBP, or SVG for web delivery, ImgShifter ships a free, browser-first tool for the job — no signup, no paywall, no upload.
