Questions & Answers

Frequently asked questions.

Everything you need to know about browser-based image compression.

Are my images really private and safe?
Yes, 100%. Unlike most online image compressors, your files are never uploaded to our servers or stored on remote cloud infrastructure. All image compression, conversion, and resizing takes place entirely in your web browser using HTML5 Canvas and WebAssembly.
Can I compress images to an exact target size like 50 KB or 100 KB?
Yes! That is one of our flagship advantages. You can select "Target size", input any limit (e.g. 50 KB or 200 KB), and our binary-search algorithm will calculate the exact quality and dimensions needed to meet your portal requirement without quality compromise.
Is this service truly completely free?
Yes, every single tool is 100% free with no paid subscriptions, no hidden daily usage quotas, and no features locked behind a paywall. There is no account creation or login required.
Which image formats are supported?
We support JPG, JPEG, PNG, WebP, AVIF, GIF, BMP, and SVG files. You can also cross-convert between JPG, PNG, WebP, and AVIF.
Can I compress multiple images at the same time in bulk?
Yes. You can select, drag and drop, or paste dozens of images simultaneously. They will be processed in parallel right in your browser, and you can download them individually or as a single bundled ZIP archive.
How does background removal work without an API or server?
We run the MODNet neural network directly within your web browser through WebAssembly and Transformers.js. The model loads into local cache and performs inference directly on your device with no API charges or privacy risk.
