100KB Extension v1.1.1: Compress & resize files in 0ms directly in Google Chrome
Resize image dimensions in pixels, mm, cm, or inches online. Crop photos in circle, square, or rounded corner shapes. Optimized to to 10KB.
Using the Resize & Crop Image to 10KB to compress your file strictly under 10KB is a requirement for many platforms. Ultra-low file size limits like this are typically enforced by legacy government databases (such as signature or thumb impression uploads) to conserve server storage. Our engine guarantees your final file will be processed to under 10,240 bytes while preserving legibility. Uploads exceeding this 0.01 MB threshold will automatically be rejected by strict databases. Application forms often require exact pixel dimensions (e.g. 600x600 px, 350x450 px, or 3.5cm x 4.5cm). Our Resize Image tool provides precision canvas scaling, DPI adjustments, and shape croppers (Circle, Square 1:1, Rounded Corners) to match official specifications.
Whether you are preparing a US Visa 600x600 pixel square photo, a Schengen Visa 35x45mm portrait, an SSC photo 350x450 pixels, an IBPS photo 200x230 pixels, or cropping profile avatars into circular shapes for social media, our engine scales canvas coordinates with bi-cubic interpolation and zero quality loss.
