Compress Images

Compress Images to an Exact File Size

Most image compressors give you a quality slider and hope for the best. CipherForces Image Compressor lets you set an exact target file size — tell it 200KB and it will hit 200KB. This is the key difference: you control the output size, not just a vague quality percentage.

The tool processes everything locally in your browser using canvas-based compression. No files are uploaded to any server, and there are no daily limits on how many images you can compress.

Common Use Cases

• Web performance: Compress hero images, thumbnails, and product photos to meet Core Web Vitals targets without manual trial-and-error.
• Email attachments: Shrink photos below the 25MB Gmail limit or 10MB Outlook limit in one step.
• Social media: Hit exact upload size limits for profile pictures, cover photos, and story images.
• Form submissions: Meet file size requirements for government forms, job applications, and university portals.

How It Compares

TinyPNG limits free users to 20 images per batch and 5MB per file. Squoosh handles one image at a time. CipherForces has no per-file size limit, supports batch processing of multiple images at once, and lets you set a precise target file size — not just a quality level.

Key Features

• Target file size: Set an exact KB or MB target and the compressor adjusts quality automatically.
• Quality slider: Or use manual quality control from 1–100 if you prefer.
• Batch processing: Drop multiple images and compress them all at once.
• Format preservation: JPG stays JPG, PNG stays PNG — no forced format conversion.

Privacy: All compression runs locally in your browser. Your images never leave your device.
