Câu hỏi thường gặp
Is the result exactly the size I pick?
The result is at or just under your target. It is rarely exactly equal, because image sizes depend on the picture, but it lands close to the limit so you keep the best quality.
Is my photo uploaded anywhere?
No. The image is processed on your own device by your browser. Nothing is sent to a server, which also makes it work well for ID photos and signatures.
What if the image is already smaller than my target?
We tell you. The tool never makes a picture bigger on purpose, so you can use the original file if it already fits.
Which formats can I use?
You can add JPG, PNG, WebP, GIF or BMP files. The result is saved as a JPEG by default, which gives the smallest files for photos, or as WebP if you choose it.
