Reduce image file size to a target KB or MB. Ideal for web and email limits. All in your browser.

JPG, PNG, WebP · Max 50MB per file · Up to 20 files
An image size reducer lets you shrink image files to a specific target size in KB or MB. Unlike a simple compressor that only reduces by quality, this tool aims for an exact file size—useful for forms that require “under 200 KB”, email limits, or platform rules (e.g. Instagram, forms). Processing runs entirely in your browser; nothing is uploaded to a server.
All processing is done in your browser. No files are sent to any server.
The tool uses your browser's Canvas API to compress images with a smart binary search. It finds the best quality that meets your exact target size (KB or MB). For very small targets, it can also downscale dimensions. Everything runs locally—nothing is uploaded.
Yes. You can add up to 20 images and reduce them all to the same target size in one go. Use "Download all as ZIP" to get a single file with all reduced images.
Each file can be up to 50MB. For larger images, compress or resize them elsewhere first, then use this tool to hit an exact size.
The reducer balances target size and quality. For JPEG/WebP it adjusts compression level; for PNG it may downscale. Very small targets may reduce quality—choose a realistic target for your use case.
Yes. All processing happens in your browser. No images are sent to any server. Your files never leave your device.
A compressor typically reduces file size by a percentage or quality level. A size reducer lets you set an exact target (e.g. 200 KB or 1 MB), which is useful for forms, email limits, or platform rules. For general compression without a specific size target, use our Image Compressor.
