Frequently Asked Questions
Will my photos lose quality?
All lossy compression removes some data, but with the Balanced preset the loss is virtually invisible to the human eye. The Aggressive preset is designed for cases where file size matters more than pixel-perfect fidelity.
Are files uploaded to a server?
No. Compression happens entirely inside your browser using the open-source browser-image-compression library. Files never leave your device — everything is processed locally for maximum privacy.
Which format compresses best?
WebP typically produces the smallest files at the same visual quality — usually 25–35% smaller than JPG. Every modern browser supports WebP natively, making it an excellent choice for web optimization.
Can I compress PNG images?
Yes! PNGs are lossless by definition, so the biggest gains come from resizing dimensions or converting to WebP/JPG if you don't need transparency. Our tool handles this conversion intelligently.
Is there a file size limit?
The uploader accepts files up to 30 MB each individually. Batches are limited only by your device's available RAM, so you can process many images simultaneously without hitting artificial limits.
What's the difference between presets?
Light (Quality ~90%) preserves maximum detail with modest size reduction (~30-50%). Balanced (Quality ~75%) offers the sweet spot for most uses (~50-70% reduction). Aggressive (Quality ~50%) maximizes compression (~70-90% reduction) for when every byte counts.
