Image Tools

15 free online tools — Compress, resize, convert and edit images in your browser

Every image tool here runs entirely in your browser: the picture is opened on your own device, processed with the canvas, and downloaded from there. Nothing is uploaded, so there is no queue, no size limit set by a server, and no copy of your photos on somebody else's disk. That makes these tools fine for private photos, client work and anything under NDA.

Crop Image Trim a photo to any size or aspect ratio, right in your browser. Add Watermark to Image Stamp a name, © line or logo on one photo or twenty at once. Position, tile, rotate, fade — all in your browser. EXIF Viewer & Remover See the hidden data in your photos — including GPS location — and remove it without quality loss. HEIC to JPG Turn iPhone photos into JPGs that open anywhere. Image to ASCII Art Convert any picture to ASCII art in your browser: choose the width, the character set and inversion, then copy the text or save a colour HTML version. Instagram Grid Splitter Split a picture into 3, 6, 9 or 12 tiles that reassemble on your profile — numbered in the order to post them. Meme Generator The classic white Impact caption with a black outline, on your own picture, in your browser. No watermark, no signup. Passport Photo Maker US 2×2 in, UK and EU 35×45 mm, Canada, India, China, Japan and more — sized exactly, with a head guide and a printable 4×6 sheet. Rotate & Flip Image Turn a photo the right way up, mirror a selfie, or tilt by any angle — one image or twenty, in your browser. SVG to PNG Converter Drop an SVG or paste its code, pick the pixel size (1×, 2×, 4×…) and background, and download a sharp raster image. Compress Image Reduce image file size by up to 90% without a visible drop in quality. Resize Image Change image dimensions by pixels, percentage or social media preset. Convert Image Convert between JPG, PNG and WebP in bulk, with quality control. Image to Base64 Turn an image into a data URI ready to paste into CSS, HTML or JSON. Favicon Generator Turn a logo into favicon.ico plus every PNG size modern browsers expect.

Which tool do you need?

Make a file smaller — the image compressor shrinks JPG, PNG and WebP by up to 90% with a quality slider, twenty files at a time.
Change the dimensions — the resizer for exact pixels or a percentage, the crop tool for a region, and the social media resizer for every platform's size in one go.
Change the format — convert between JPG, PNG and WebP, turn an iPhone photo into a JPG with HEIC to JPG, or rasterise vector graphics with SVG to PNG.
Fix orientation or add text — rotate and flip, add a watermark, or caption a meme.
Privacy and print — strip location data with the EXIF remover, or make a passport photo at a real 300 DPI.

JPG, PNG or WebP?

JPG is for photographs: small files, no transparency, a little loss each time it is saved. PNG is lossless and keeps transparency, so it suits logos, screenshots and graphics with sharp edges — at a larger size. WebP does both jobs at roughly a third smaller than either and is supported by every current browser; it is the right default for anything going on a web page, and the wrong choice for a file that has to open in old software. The converter and compressor both let you pick.

Why browser-side matters

Most online image tools upload your file to a server, process it there and keep it for a while. For a holiday snap that is harmless; for a scan of a passport or a client's product photos it is not. Processing in the browser removes the question entirely — the file never leaves the device — and it is faster, because there is no upload and no download. The trade-off is that very large batches depend on your own machine's memory, which is why the tools cap at twenty files at a time.
