The tool accepts a single image and compresses it to the file size limit you specify, converting the result to JPG format. You choose a specific threshold from the list: 50, 100, 200, 300, 500 KB, or 1 MB. The algorithm automatically adjusts quality parameters so that the final file size does not exceed the set limit, as far as possible.
When this is useful
You are filling out an online form on a government portal that requires attaching a passport scan, and the system strictly limits the attachment size to 300 kilobytes. Your original scan is several megabytes, and you use this tool for precise adjustment. Another example: a forum or classifieds site allows uploading avatars no larger than 100 KB, and you need to meet this limit without manually tweaking settings in a graphics editor.
Step-by-step instructions
- Click the upload area and select the source photo or scan file from your device.
- In the dropdown list or settings panel, mark the desired size limit, for example, 100 KB.
- Start the processing by clicking the corresponding button.
- Wait for the operation to complete and download the finished JPG file, whose size is guaranteed not to exceed the chosen threshold.
How to verify the result
If the final file still slightly exceeds the limit, try selecting the next lower value from the list of available thresholds. Ensure you are uploading a single image, not a multi-page document, as the tool is designed for processing one file. Check the source format: although PNG and HEIC are supported, the output is always a JPG, which may result in the loss of transparency.
Important limitations
The tool always converts the result to JPG format, so the transparency of the original PNG will be replaced with a white background. It is not intended for batch processing a folder of photos or for compressing animated images. Achieving the exact size limit does not guarantee the preservation of the original level of detail, as quality inevitably degrades with strong compression.
