How FileNova Image Compression Works
Understand quality settings, target file sizes in KB, and in-browser optimization behavior.
Target Max KB Sizing
Need to compress an image to 50KB or 100KB for an application portal? Enter your target limit, and our iterative algorithm dynamically calibrates compression quality and, if necessary, scales dimensions to approach your desired file size.
Quality vs. File Size
Adjust the quality slider to find your ideal balance. Higher quality values retain fine photographic details for print, while lower values prioritize maximum data reduction for fast web page load speeds.
PNG Color Quantization
For PNG graphics, FileNova applies intelligent color quantization on image data when lower quality profiles are selected, achieving true byte reduction while preserving transparent backgrounds.
Non-Inflation Guarantee
If re-encoding an already-optimized photo results in a file larger than your original upload, FileNova automatically retains your original file so you never receive an unexpectedly inflated image.

Frequently Asked Questions
Fact-based answers regarding compress image capabilities, security, and format support.
How much file size reduction can I expect?
Typical image file size savings range between 40% and 80% depending on the source resolution, image complexity, and selected quality profile.
Will image compression degrade visual sharpness?
FileNova uses smart browser-based quantizers and resampling algorithms that strip unneeded metadata and compress pixels while preserving crisp details.
Is transparent PNG and WebP transparency preserved?
Yes. Full alpha channel transparency in PNG and WebP images is maintained 100% intact throughout the compression process.
Are my photos uploaded to a cloud server?
No. All compression algorithms run locally in your browser memory using WebAssembly. Your photos never leave your device.
