Metadata (EXIF) is removed in the output for privacy and smaller file size. Orientation is auto-corrected.
An image size reducer lets you shrink image files to a specific target size in KB or MB. Unlike a simple image 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). You can also convert PNG to JPEG or WebP for smaller output via the output format option (like a PNG to JPEG converter or WebP converter). All processing runs in your browser; nothing is uploaded.
This tool runs entirely in your browser. Your images never leave your device—no uploads to any server. You get the same reduce image size online experience with full privacy. Use it as a bulk image compressor by adding multiple files and reducing them all to your target (e.g. 100KB or 1MB) in one go.
All processing is done in your browser. No files are sent to any server.
The tool uses a binary search on quality (for JPEG/WebP) or scale (for PNG) so the output stays within 2% of your target. If quality alone can’t reach the target, it progressively downscales the image and tries again. Optional conversion to JPEG or WebP lets you shrink PNGs further by trading transparency for a smaller file. Everything runs in your browser with no uploads.
Use the target size presets or enter a custom value to reduce image to 100KB, reduce image to 200KB, or keep output under 1MB. The same tool works for any target. Reduce PNG size without losing more quality than needed; convert PNG to JPEG for smaller file when you don't need transparency.
A private image compressor that runs only in your browser never sends files to a server. Metadata (EXIF) is removed in the output for privacy and smaller size.

Reduce image size online to meet strict file limits for passport photo uploads, government forms, job applications, and website optimization. Many portals require images under 100KB, 200KB, or 1MB—this free tool lets you compress image to that exact size in your browser with no uploads. Perfect for visa photos, ID uploads, and faster page loads.
Upload your image, set the target to 100 KB using the presets or the number field, then click Reduce. The tool uses a binary search to find the best quality that meets 100KB. You can also reduce image to 200KB or any other target the same way.
Set the target size unit to MB and the value to 1 (or use the 1 MB preset). Click Reduce—the output will stay within 2% of 1MB. Works for JPG, PNG, and WebP. All processing runs in your browser; no uploads.
Use the target size (e.g. 100KB or 200KB); the tool minimizes quality loss while hitting the size. For even smaller files, choose "Convert to JPEG" or "Convert to WebP" in Output format—you can set a background color for transparent PNGs. This reduces PNG size significantly.
Yes. This is a bulk image compressor: add up to 20 images and reduce them all to the same target in one go. Use "Download all as ZIP" to get a single file with all reduced images. Processing runs in your browser.
Yes. All processing happens in your browser. No images are sent to any server. Your files never leave your device. No data is stored or logged. 100% private and safe.
The tool uses your browser's Canvas API with a binary search to find the best quality that meets your exact target size (KB or MB). For JPEG and WebP it adjusts quality; for PNG it may downscale. Optional format conversion (PNG to JPEG/WebP) can produce much smaller files. Everything runs in your browser—nothing is uploaded.
A compressor typically reduces file size by a percentage or quality level. A size reducer lets you set an exact target (e.g. 100KB, 200KB, 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.
Yes. Use the "Output format" option and choose "Convert to JPEG" or "Convert to WebP." For transparent PNGs you can set a background color (e.g. white) so the result looks correct. Use our PNG to JPEG or WebP conversion via the same tool for much smaller files.
