CodeKitHubImage Tools
Convert and compress images — right in your browser, no upload.
Every image tool on this page runs entirely in your browser: files are processed on your own device and never uploaded to a server. That is not a marketing line — it is how the tools are built, and it is why there are no file-size limits, no queues and no watermarks anywhere in this category.
The tools fall into three groups: format converters (when software refuses a format), compressors (when a file is too big), and the resizer (when the dimensions are wrong). Picking the right group first saves the most time.
Which tool do I need?
- Image Compressor — The file is too big but the format is fine — start here. Handles JPG, PNG and WebP with a quality dial.
- Image Resizer — The dimensions are too large (e.g. a 4000px photo for an 800px slot). Resizing first also shrinks the file dramatically.
- HEIC to JPG Converter — iPhone photos that Windows or an upload form refuses to open.
- WebP to JPG Converter — Images saved from websites that older software cannot open.
- PNG Compressor — Screenshots, logos and UI graphics that must stay PNG (transparency) but weigh too much.
- SVG Converter — A vector logo that needs to become a normal PNG/JPG at some exact size.
- GIF Compressor — An animated GIF that is embarrassingly large.
