Offline Client-Side Image Processing Engine
img-converter.in processes your files completely inside your web browser. No files are uploaded to any server. Utilizing next-generation HTML5 Canvas operations, async Web Workers, and local memory pipelines, you get instant format conversions and size compressions while retaining 100% data privacy.

Frequently Asked Questions
How does offline browser compression keep images private?
img-converter.in operates solely via JavaScript APIs within your local browser sandbox. Standard online converters transfer files to distant backend servers to process them, risking privacy. img-converter.in uses Canvas memory structures, so files never travel over the network.
Can I compress images to exactly 100 KB or 200 KB?
Yes, using our Target Size compression loop, the converter dynamically calculates quality variables and scale sizes to automatically match or fall just below your specified limit, bypassing guess-work sliders.
Are EXIF metadata parameters stripped?
Yes. By default, drawing and reading pixel coordinates on an HTML5 canvas discards internal metadata header chunks (containing GPS tags, cameras, timestamps). This acts as a native EXIF stripper.
