Free Image Resizer

What it does

Change aspect ratio of image online free. Image resizer to change image size, reduce resolution, and optimize for social media. No signup needed.

Free online image resizer — resize images in KB (20KB, 50KB, 100KB, 200KB), in pixels, or in cm for print and passport photos. Bulk resize supported. No upload, no sign-up — everything runs in your browser.

A simple image resizer that hits exact targets: a file size in KB, exact pixel dimensions, or a physical print size in cm. Bulk supported. Everything runs in your browser — nothing is ever uploaded. Common: passport photo 3.5 × 4.5 cm · US passport 5.1 × 5.1 cm. Photo is centre-cropped to fit the exact shape. Files are processed one at a time, entirely on your device. Larger batches take longer but never leave your browser. Most tools make you pick between a compressor, a pixel resizer, and a print tool. This free online image resizer does all three, because real tasks usually mix them — an exam form wants a photo under 50KB and at a certain pixel size; a passport office wants 3.5 × 4.5 cm…from imageresizer.tech

  I spent 6 years building a ridiculous wooden pixel display▲1,145

  I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

  I was curious about spherical helix, ended up making this visualization▲865

  I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
