Guide
Reducing image file size is essential for meeting upload limits, speeding up web pages, and making files easier to share via email and messaging apps. Large image files from modern cameras and smartphones can exceed 10MB each, which is often too large for web upload forms, email attachments, and mobile data plans. This tool applies targeted compression to shrink file sizes while maintaining acceptable visual quality, with a real-time preview so you can see exactly how the output compares to the original before downloading.
This tool is designed for the specific task of making image files smaller through compression, without changing pixel dimensions. Use it when an image is too large to upload, email, or share, but you do not need to change its width or height.

FAQ
Reducing file size (compression) decreases the amount of data stored in the file by applying more aggressive compression algorithms, while keeping the pixel dimensions the same. Resizing changes the actual pixel dimensions (width and height), which also reduces file size but makes the image physically smaller. This tool focuses on compression-based file size reduction without changing dimensions. If you need to change pixel dimensions, use the Resize Image tool instead.
Most JPG photographs can be reduced to 30-50 percent of their original size before visible artifacts appear, depending on the initial quality. PNG files typically see more modest reductions (10-30 percent) through optimization. The key is to preview the output and compare it with the original. For web use, a file that looks identical at normal viewing distance is usually acceptable, even if pixel-peeping reveals minor differences.
Yes, aggressive compression can reduce print quality, especially for large prints. For print purposes, keep file sizes larger (quality 90+ for JPG) or use lossless formats like TIFF or PNG. File size reduction is most beneficial for web, email, and screen display where the image is viewed at limited resolution. If you need both web-optimized and print-quality versions, create two separate files from the original.
PNG is lossless, so its compression has limits. Typical PNG optimization achieves 10-30 percent size reduction by removing unnecessary metadata and applying better compression algorithms. For more dramatic size reduction, consider converting to WebP (which supports lossless mode with better compression) or JPG (if the image is a photograph). This tool works best with JPG and WebP files where lossy compression can achieve significant size reductions.
