    What is image compression?

    Image compression reduces file size by removing redundant data while preserving visual quality. Lossy compression (JPEG) achieves 60–80% size reduction with minimal perceptual difference — ideal for web, social media, and email.

    Pages with optimized images load 3.5× faster on average [HTTP Archive, 2024]. Compressed images reduce bandwidth costs by up to 70% [Cloudflare, 2024].

    Trndinn's compressor uses smart algorithms to find the optimal quality-size balance. Everything runs in your browser — images never leave your device.

    Frequently asked questions

    Can I compress a PNG without losing transparency?
    Yes. Trndinn's PNG compressor preserves the alpha channel during compression, so transparent backgrounds remain intact after reducing file size.
    What is the best way to compress a PNG file?
    For most use cases, a quality setting of 70-85% reduces PNG file size by 60-80% while keeping the image visually lossless. Trndinn's compressor handles this automatically in the browser.
    How much smaller can a PNG get after compression?
    PNG files can typically be reduced by 40-80% depending on image content. Images with large flat-color areas compress most aggressively.
    Is PNG compression lossless?
    Standard PNG compression is lossless. Trndinn also supports lossy PNG compression (reducing color palette), which yields smaller files at a slight quality tradeoff.
    Why is my PNG still large after compression?
    High-detail photos saved as PNG retain many color values that resist compression. Consider converting to WebP or JPG for photos — PNGs compress best on graphics, logos, and illustrations.
    How much can I compress a JPG without losing quality?
    Most JPGs compress to 70–80% quality with no visible difference. The “Smart” preset finds this sweet spot automatically. For web, 65–75% reduces file size by 60–80%.
    Is my data safe when compressing images online?
    Yes — Trndinn’s compressor runs entirely in your browser using the Canvas API. Images are never uploaded. When you close the tab, all data is gone.
