Upload Your Image
Drag and drop your image onto the upload zone, or click Browse Files to select it. Supported formats include JPEG, PNG, and WebP.
Automatic Compression
The tool runs a binary search to find the compression quality level that brings the output as close to your target file size as possible without exceeding it.

Frequently Asked Questions
Image Size Reducer targets a specific output file size in KB. You set a goal (for example, 100KB) and the tool automatically finds the compression level required to meet it. Image Compressor instead lets you set a quality percentage and shows you the resulting file size. Use Image Size Reducer when you must meet a specific size limit (forms, portals, email restrictions). Use Image Compressor when you want quality control and the output size is flexible.
Government portals, job application systems, university admission forms, and many business platforms impose file size limits (often 50KB, 100KB, or 200KB) to manage storage requirements and standardise uploads. These limits are common for passport sized photos and document scans.
The tool uses binary search across compression quality levels to get as close to your target as possible. In most cases, it achieves within a few kilobytes of the target. Very small targets (below ~20KB for a complex photograph) may require such heavy compression that visible quality loss becomes significant.
You can set a custom target as low as 5KB. At very low targets, image quality will visibly degrade. The tool will always get as close as possible to the target, but cannot guarantee exact file sizes for all inputs.
You can upload JPEG, PNG, WebP, BMP, and most standard image formats. The output is typically a JPEG file, as JPEG allows the widest range of quality levels for size targeting.
Yes. Many passport photo and visa application portals require images below 50KB or 100KB. Set the target to match the portal's requirement, upload your photo, and download the compliant file. Verify that the output still meets any resolution or dimension requirements separately.
No. This tool only adjusts compression quality, not pixel dimensions. The width and height of the image remain unchanged. If you also need to change dimensions, use the Image Resizer separately.
If the uploaded image is already below the target size, the tool will download the image with minimal further compression, since no reduction is needed.
No. All processing runs inside your browser. No image data is transmitted to any server.
The input field accepts values in KB. To target 1MB, enter 1000 in the KB field. To target 500KB, enter 500.
