Frequently Asked Questions
We answer your questions about privacy, features, and limits.
How to compress the weight of my images in batch safely and privately?
Using our smart compressor, just drag all your files in bulk. The local process will optimize each photo using your device's GPU without ever touching the cloud.
What does smart optimization through lossless compression mean?
It is a mathematical mechanism to remove redundancies, unnecessary profiles, and metadata in the image encoding that decrease the file's KB without visually damaging the graphic.
How much weight in kilobytes (KB) or megabytes (MB) can I save by optimizing my photos?
Depending on the original image, compression levels typically range between 50% and 80%, translating heavy MB into friendly ranges of mere KB for the web.
How does manipulating the percentage slider affect the final quality of the file?
Decreasing the percentage will increase size savings, but approaching very low values (under 30%) can trigger slight visible quality loss through destructive compression.
What is the recommended quality level for compressing images intended for the web?
A visual balance is recommended (usually the default value of 80%). This upper limit is sufficient for quick consumption without sacrificing visual edge definition.
Can I optimize my photo storage directly from a mobile device?
The application is fully functional on modern mobile architectures. You can free up space by compressing your media library from your mobile securely and through touch.
Why do my locally compressed images improve speed on Shopify or WordPress?
By weighing fewer KB, the servers dispatching your images use less connection time and download almost instantly for your visitors, which benefits the SEO of those platforms.
What kind of hardware resources does the dynamic compressor use from my computer?
It uses multi-core processing in JavaScript, simultaneously leveraging the CPU and RAM available on your computer without downloading external libraries.
Is it possible to verify the exact weight of my files before and after processing?
Yes, for each item in the output queue, you will be able to view and interact in detail with its original size versus its new final format weight to verify the savings impact.
Is there any risk of my photographs suffering pixelation when drastically reducing their weight?
Aggressively reducing file weight through low-quality JPG could result in some fragmentation (artifacts); however, our dynamic compressor seeks to mitigate this by adjusting smoothing algorithms.
