PhotoRiyaHow to compress an image to 100KB
Drop your photo onto the box above. The tool aims for 100 KB and shows the result straight away, along with the quality it used. Change Largest file size if you need a different limit, switch the unit to MB, or choose Pixels to set the size yourself before compressing. Press Download when you are happy.
Many websites, government forms and job applications ask for a photo under a set size. This does the work for you: no guessing quality values and re-saving until it fits.
How it reaches the size
File size depends on how detailed the picture is and how big it is. The tool saves your photo as a JPG and searches for the highest quality that still fits under the limit, so the picture looks as good as possible at that size.
If even the lowest quality is too big, as with a large camera photo, the picture is made smaller until it fits, using a high-quality Lanczos filter. If you need to keep the pixel size, untick Make the picture smaller if it has to be, and the tool will say when the limit can't be reached.
Tips
Photos with large smooth areas, such as portraits and skies, compress better than busy ones. For PNG screenshots with text, resizing often saves more than lowering the quality. To change the size without a limit, use resize image, and for plain compression see the image compressor.
Questions people ask
How do I compress an image to 100KB?
Drop your photo onto the tool above. It targets 100 KB by default, so it is compressed to fit right away. Then press Download.
Will the quality drop a lot?
The tool picks the highest quality that fits, so the loss is as small as it can be for that size. A big camera photo needs more reduction than a small web picture.
Does it keep the same dimensions?
Only when it can. If the photo is too detailed to fit at full size, the tool makes it smaller by the least amount needed. Untick the option to keep the dimensions and see whether the limit can be reached.
Which format is the result?
JPG. It is the only common format where quality, and so file size, can be tuned precisely. PNG and WebP here are lossless and can't be tuned to a set size.
Is my photo uploaded to a server?
No. The resizing and compressing happen inside your browser tab, on your own device, and nothing is sent anywhere. That also makes it instant, with no upload or queue.
Is it free?
Yes. There is no limit, no watermark and no account. PhotoRiya is open source under the MIT and Apache 2.0 licenses.
