常见问题
Are these image tools really free?
Yes, every tool is free with no limits on how many images you process. The site is paid for by advertising, which is why you see ads on the page. There is no premium tier and no account to create.
Do I need to install anything?
No. Everything runs in your web browser on any phone, tablet or computer. There is nothing to download and nothing to keep updated.
What happens to my images after I upload them?
Your image is processed on our server and then deleted automatically within one hour. We do not look at your files, do not share them, and do not use them to train anything.
Which image formats are supported?
We read JPG, PNG, WEBP, HEIC, TIFF, BMP and GIF, and write JPG, PNG, WEBP, TIFF, BMP and GIF. HEIC support means iPhone photos work without converting them first.
Can I use these tools on my phone?
Yes. The whole site is built for phones first — you can pick an image from your gallery, take a new photo with the camera, and crop with your finger.
Is there a file size limit?
Each file can be up to 50 MB, which comfortably covers photos from any phone or consumer camera. You can process several files in one go.
