How can I make a photo smaller in file size without visible quality loss?
In Lunyce, add one or several images, choose the quality and the maximum size, then download the lighter files. The "Recommended" setting usually cuts the file size by 3 to 10 times with no visible difference on screen. Your photos are processed on your device and never uploaded; it is free, unlimited and needs no account.
How to
- Add your images (several at once if needed).
- Choose the quality and the maximum size.
- Start, then download the lighter images.
Frequently asked questions
Which setting should I choose?
"Recommended" usually cuts the size by 3 to 10 times with no visible difference on screen. Choose "High" for a photo you will print.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
