Compress Image to 100KB - Exact Size Reducer Online

About This Tool

Introduction

Compress Image to Exact Size is a free online tool that shrinks any photo to a precise file size, such as 100KB, 50KB or 200KB. Job portals, government forms, exam applications and online marketplaces often reject uploads above a strict KB limit. Instead of guessing quality settings, enter your target size and the tool tunes JPEG, WebP or PNG compression automatically until the file fits.

How to Use

1. Drop an image into the upload area or click to browse your device.
2. Type your target size in KB, or tap a preset like 50, 100, 200 or 500 KB.
3. Choose JPEG for photos, WebP for smaller web files, or PNG for lossless quality.
4. Click Compress Image, review the before and after sizes, then download.

Key Features

• Exact target sizes: dial in any KB value from 5 KB to 50000 KB.
• Smart quality search: binary search finds the highest quality that fits your limit.
• Three output formats: JPEG, WebP and PNG with automatic dimension fallback.
• 100 percent private: images are processed in your browser and never uploaded.
• No signup, no watermark, no file limits.

Why Choose Trencada

Most online compressors only offer low, medium and high presets and leave you guessing. Trencada hits your exact KB target in one click, shows the real before and after numbers, and keeps your files on your own device.

FAQ

Will my image still look good at 100KB? The tool always keeps the highest quality setting that fits your target, so photos stay sharp. Very small targets on huge photos may reduce dimensions slightly.

Which format should I choose? JPEG is best for photos, WebP gives smaller files in modern browsers, and PNG is ideal when you need lossless quality for graphics.

Is there a file size limit? You can upload images up to 50MB. The target size can be set between 5 KB and 50000 KB.
