Target Size Compressor

Compress images to a specific file size target, automatically finding the highest quality that fits within your byte budget. Specify your maximum in KB or MB, and the tool iteratively adjusts compression until achieving your target with optimal quality preservation.

The compression algorithm uses binary search to efficiently find the quality setting that produces exactly the file size you need. Rather than guessing at quality percentages, you specify the outcome you require and the tool works backward to achieve it. Preview the result to verify visual quality meets your standards before downloading.

Forum users meeting avatar and attachment size limits hit exact requirements without trial-and-error quality adjustments. Email senders preparing attachments for recipients with slow connections or strict mailbox limits optimize for specific byte budgets. CMS administrators uploading to systems with file size restrictions ensure uploads succeed on first attempt. Mobile app developers targeting specific asset sizes for bundle optimization hit precise targets. Anyone facing a hard file size limit—rather than a quality preference—will find target-based compression eliminates guesswork entirely.
