How FileNova Compresses Images

  1. 1

    Upload your image

    Upload any JPG, PNG, or WebP image up to 25 MB. FileNova immediately measures dimensions and original file size.

  2. 2

    Choose compression level

    Select Light for minimal quality loss, Balanced for standard sharing, or Maximum for maximum file reduction.

  3. 3

    Inspect savings & download

    Review your compression percentage and total bytes saved, then download your optimized image immediately.

Not sure which level to pick? Start with Balanced — it's the best default for most images. If the file is still too large, try the Resize Image tool first to reduce dimensions, then compress.

Frequently asked questions

6
How do I reduce the size of an image?
Upload your JPG, PNG, or WebP image to the tool above, pick a compression level, and download the optimized copy — the result screen shows how much you saved. The how to compress a PDF guide covers similar principles for documents.
Does compression affect image quality?
Yes — compression always involves a trade-off. Light compression keeps quality nearly identical to the original. Balanced is the sweet spot for most uses: sharp enough for web and print, with significant size savings. Maximum prioritizes the smallest file size and will show visible artifacts on close inspection.
Which compression level should I choose?
Balanced fits most images: a solid size cut with quality that stays comfortable to view. Choose Light when the image must stay as close to the original as possible (e.g., product photos, portfolios), and Maximum when the upload limit is hard and readability matters more than polish.
What is the maximum file size?
You can upload images up to 25 MB. If an image is still too large after Maximum compression, it usually needs resizing rather than squeezing — the Resize Image tool can reduce dimensions before compressing.
What happens to transparent PNGs?
PNG transparency is preserved at all compression levels. At Light and Balanced levels, the tool uses lossless PNG optimization. At Maximum, it may convert to lossy WebP if that yields a smaller result — transparency is still supported in WebP.
Are my images uploaded to a server?
Yes, the image is sent to FileNova's server for processing, but it is processed in memory and never written to permanent storage. The optimized image is streamed back to you immediately with a no-store cache policy. Nothing is retained after the request completes.
