Enter your target KB value and click Resize. The tool loops through quality levels until the file fits.
Your resized file downloads instantly as a JPEG. Ready to upload to any form, platform, or portal without extra steps.
Common use cases
When a platform has an unusual size limit — 75KB, 150KB, 500KB — a fixed-target tool does not help. This tool lets you type in any KB value and compresses your image to that exact threshold, no matter the number.
Any KB value, any platform
Different platforms have wildly different upload size limits. LinkedIn company logos: 4MB. WhatsApp profile: varies by platform version. Indian exam portals: 10–50KB. Travel visa forms: 200–400KB. Instead of hunting for a tool that matches your exact limit, just type it in here.
Frequently asked questions
How do I know what KB limit my platform requires?
Check the upload instructions on the form or platform settings page. It usually says something like 'maximum file size: 150 KB' or 'image must be under 300 KB'. Enter that number into the target KB field.
Can I enter decimal values like 50.5 KB?
The tool accepts whole numbers only. For decimal targets, round up to the nearest integer — for example, enter 51 for a 50.5KB limit.
What is the minimum KB I can target?
Practically, the tool can compress down to around 5–10KB for small images. For very aggressive targets on large images, the visual quality will degrade significantly.
Why might the result be slightly above my target?
The compression algorithm works in discrete quality steps (10% increments). It stops once it first falls below your target size, so the actual result is usually at or just under the limit.
