Image Compressor: Frequently Asked Questions
How do I compress a photo without losing quality?
Our image compressor allows you to manually adjust the quality slider. We recommend a quality setting between 70% and 80%, which drastically reduces file size while making the quality difference virtually unnoticeable to the human eye.
Can I convert PNG to WebP or JPG while compressing?
Yes! After uploading your image, you can select your preferred output format. You can easily upload a large PNG, compress it, and download it as an optimized, next-generation WebP or a standard JPG.
Is there a file size limit for image compression?
Because our tool runs entirely locally in your web browser, there are no artificial file size limits or paywalls. You can process large raw files instantly as long as your device has enough memory.
Are my photos uploaded to a server?
No. Absolute privacy is guaranteed. The image optimization runs inside your own browser using local processing algorithms. Your images never leave your device.
