Step 1: Check the size and format
The tool above is preselected to 250 KB. Choose one JPEG, PNG or WebP image from your device. If a service specifies JPG or another supported type, use the Output format control to match it.
Private exact-size compression
Use this page to make an image fit under, below, less than, up to or maximum 250 KB. It is useful for document uploads, profile images and email attachments when you need a specific target size without sending the image to a server.
Private image compressor
Choose one image, set the limit, and download a verified result. Your original is never changed.
Use this only when a form requires your image to be between two file sizes.
Resize image
Enter a width, a height, or both. No crop or fill is applied in this step.
Choose an image to preview planned dimensions.
Aspect ratio is off. Exact width and height may distort the image.

Instructions for this target
Discord requires custom emoji images smaller than 256 KB. A 250 KB target leaves a modest safety margin; Discord does not specify 250 KB exactly.
The tool above is preselected to 250 KB. Choose one JPEG, PNG or WebP image from your device. If a service specifies JPG or another supported type, use the Output format control to match it.
Use a simple, legible image and the accepted output format. Discord has separate emoji-size and display guidance, and the compressor does not automatically crop to 128 by 128.
If you enter a width or height, use Resize and compress and keep Keep aspect ratio checked to avoid stretching. Resize only does not enforce a file-size limit.
Select the compress button, inspect the before-and-after previews and check the output size and dimensions. Download only after the size verifies below 250 KB and the image still looks suitable.
A file-size pass does not mean it meets every third-party image requirement.
Verified example of an upload limit
Discord's limit is smaller than 256 KB. The 250 KB target is a safety margin, NOT a Discord requirement.
Relationship to this preset: Safety margin below published maximum. This is a maximum or safety margin, not an instruction to produce a file of exactly 250 KB.
Official upload requirements Checked 2026-10-28. The service's current rules take precedence.
Nearby exact sizes
Medium KB targets often balance acceptable visual quality with common upload limits. The workbench keeps the selected target editable if you need a nearby exact size.
