Reduce image to 50KB or less

Select 1 JPEG, PNG, WebP, or HEIC image to prepare an image for a profile or application form requiring 50KB or less. The default file size limit is 50KB and the default save format is JPEG. Change the format or maximum dimensions as needed, compare the images before and after processing and their actual file sizes, and save a result within the limit. 1KB is treated as 1,000B.

Add files

You can also drop a file to add it
Advanced settingsNo dimension limit
Transparent areas：White

You can leave these fields blank. The image fits within the specified bounds while keeping its aspect ratio, without being enlarged. It may be reduced further to meet the file size limit.

In JPEG, transparent areas are filled with this color.

What you can do

50KB set by default

Select an image and adjust it toward 50KB or less. You can change the limit to match submission requirements.

Check file size and appearance together

Compare the actual byte count, dimensions, and images before and after processing, then save a result within the limit.

How to use

  1. Select an image

    Select 1 JPEG, PNG, WebP, or HEIC image.

  2. Check and adjust settings

    The default file size limit is 50KB and the default save format is JPEG. Change them only if needed, then run the tool.

  3. Check the result and save

    Check the actual file size and image. Confirm that text and details are readable and that the dimensions and format also meet the submission requirements, then save.

Useful when

Submit a profile image

Adjust the image while checking the face and outlines when 50KB or less is required.

Fit a small attachment limit

Process images one at a time to prepare files for forms with strict attachment limits.

What to check even after meeting the file size limit

Enlarge the image to check text and details

Fitting an image within the small 50KB limit may reduce image quality or dimensions. Enlarge the processed image and check whether the parts you need can be distinguished.

Limits are checked against the actual byte count

This tool treats 1KB as 1,000B. 50KB is 50,000B. Whether the limit is met is not determined solely by the rounded KB display.

Formats and transparent areas

JPEG fills transparent areas with the background color. PNG and WebP preserve transparency. Choose the format required by the submission destination.

Frequently asked questions

Will the result always be exactly 50KB?

The tool aims for the specified limit or below. The result will not be exactly that size, and image quality or dimensions may change to fit the limit.

What if text becomes hard to read?

Review the save format and submission requirements as well as file size. If a small limit and readable detail cannot both be achieved, check whether the recipient can accept a higher limit.

What if the image does not fit the target file size?

Increase the file size limit or change the save format and try again. Files that do not meet the limit are never saved as successful results.
