All-in-One Image Tools
Convert images to WebP — smaller files, same look.
Shrink file size while keeping the image quality.
Resize to any dimension — great for icons and thumbnails.
Grayscale, sepia and more — right in your browser.
Generate a normal map from a height map. DirectX / OpenGL ready.
80–90 is recommended. Lower quality means smaller files.
80–90 is recommended. Lower quality means smaller files.
PNG is lossless, so savings are small. Pick JPEG or WebP for a big reduction.
Enter width only and the height is calculated automatically.
100% applies the filter fully; lower values blend with the original.
Ready
Everything runs in your browser — no image is ever uploaded to a server.
How to use it
- Drag and drop your images, or click “Choose files”. Several files at once work fine.
- Pick the tab for the tool you want.
- Adjust the settings and hit “Convert”.
- Press “Download” — two or more files are bundled into a ZIP automatically.
Everything from loading to converting happens inside your browser. Nothing is sent to a server, so unreleased artwork and client files are safe here.
The five tools
🖼 WebP
Converts PNG and JPG files to WebP. File sizes drop sharply with almost no visible change, which makes it a quick win for page speed. A quality setting of 80–90 is a good starting point.
🗜 Compress
Keeps the format and cuts the file size. After converting you get the original size, the output size, and how much you saved. For a bigger reduction, switching the output format to JPEG or WebP is recommended.
📐 Resize
Resizes to any dimension, with presets for 4K, Full HD, HD, 800px and 400px. Enter only the width and the height follows automatically, keeping the aspect ratio. Handy for icons and thumbnails.
🎨 Filters
Six of them: grayscale, sepia, pixelate, invert, vintage and threshold. Lower the strength slider and the effect blends with the original, so anything that lands too heavy can be dialled back.
🧱 Normal map
Generates a normal map from a height map. DirectX and OpenGL disagree about which way the green channel points, so flip modes are included. Useful for texture work in Blender and Unity.
Chain them together
The one button worth knowing about is “Use result as new input”.
Press it after a conversion and the output becomes your next input. For example:
A 2000px photo → Resize it to 800px → Filter it to sepia → Convert it to WebP
All of it on one screen, without saving a single intermediate file.
