12 tools, no uploads
Free online image tools. Edit the photo; never upload it.
12 image utilities — compressing, resizing, converting, cropping, watermarking and cleaning up metadata — each documented down to the codec behaviour it depends on. They run in this browser tab, which means a photograph with your home coordinates written into it is never handed to a website in order to be made smaller.
- Image CompressorShrink a photo without visible loss
- Batch OptimizerCompress many images and download a ZIP
- Image ResizerResize with high-quality resampling
- Crop, Rotate & FlipTrim, turn and mirror an image
- Convert to WebPJPG and PNG to WebP
- WebP to JPG or PNGConvert WebP for tools that refuse it
- JPG ↔ PNGConvert between JPG and PNG
- SVG to PNGRasterize SVG at any scale
- EXIF Viewer & RemoverSee and strip photo metadata, including GPS
- Add WatermarkOverlay text on an image
- Color Palette ExtractorPull the dominant colours from an image
- Favicon GeneratorA full favicon set from one image
On your device
Why the images are processed on your device
A photograph carries more than the picture. A phone writes GPS latitude and longitude, a capture timestamp, the device make and model, and often a body or lens serial number into the file's EXIF block, so uploading a holiday photo to a compression site discloses where you were standing and which camera you own — and once those bytes are on someone else's server you cannot un-send them, whatever the retention policy says. Here nothing is sent. Files are read from disk with the File API, decoded into a Canvas or an OffscreenCanvas inside a Web Worker, resampled with a Lanczos kernel, and re-encoded either by the browser's own encoder or by a WebAssembly codec compiled into the page — @jsquash/webp handles WebP everywhere, because Safari still cannot produce it from canvas.toBlob. EXIF removal goes further and never touches the pixels at all: the JPEG's APP1 and COM marker segments are dropped at the byte level while the entropy-coded scan data is copied through unchanged, so the image is bit-identical and the ICC colour profile survives. You can check all of this rather than believe it: open your browser's network inspector, compress or convert an image, and watch that no request carries the file. The same property is why every tool keeps working with the network disconnected.
Questions
Image tools here, answered
Are my images uploaded to be processed?
No. Every tool decodes, edits and re-encodes inside this browser tab. Open your network inspector, run a conversion, and confirm that no request contains the file — that check takes ten seconds and is worth more than any privacy policy.
Do the image tools work offline?
Yes. Once a page has loaded there is no backend to call, so compression, resizing and conversion all keep working with the network off. That falls out of the design rather than being an added feature.
Is there a file size or count limit?
No plan limit, but there are real device limits. Batches are processed one image at a time to stay within mobile memory, and iOS caps canvas area at roughly 16.7 megapixels — 4096×4096 on older devices — so very large images are clamped rather than silently coming out blank.
Which image tools are available?
Compression, batch optimisation, resizing, crop and rotate, WebP conversion in both directions, JPG and PNG conversion, SVG rasterisation, an EXIF viewer and remover, watermarking, colour palette extraction and a favicon generator — each with its own page.
