Don't trust us — verify it

Other “privacy-first” image tools still upload your file to a server. ImgShifter doesn't. Here's a 30-second test you can run yourself, with nothing to install.

About ImgShifter

Free online image converter, compressor, cropper, and resizer — no upload

What every tool does and how your files stay on your device, TIFF and RAW included.

Image format conversion

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.

Compress, crop, and resize

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 WEBP compression via the jsquash MozJPEG and libwebp encoders, lossless PNG optimisation via Oxipng, and SVG rasterise/vectorise as a pure-JavaScript Canvas pass — so your image never leaves your device.

Verifiable no-upload privacy

What makes ImgShifter 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.

TIFF and RAW, decoded locally

Even the advanced formats stay on your device. TIFF to JPG and TIFF to PNG decode with UTIF.js in a background worker, covering LZW, ZIP, JPEG, and PackBits compression, 16-bit color, and fax TIFFs. RAW to JPG develops Canon CR2 and CR3, Nikon NEF, Sony ARW, Adobe DNG, and other camera RAW files with LibRaw compiled to WebAssembly, using the camera’s white balance — or pulls the camera’s own embedded JPEG when you want its look. 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.

Your images stay yours.

Drop a file and see for yourself. No signup, no upload, no watermark.
