- Process images at the largest size you will need — you can always downscale later, but upscaling loses quality.
- Combine Image Compressor with other FlexyPdf image tools for a complete workflow.
- Close unnecessary browser tabs to free up memory for processing large or high-resolution images.
Common Problems & Solutions
The image quality looks degraded after processing.
Check the quality/compression settings. Increase the quality slider or choose a lossless format like PNG for pixel-perfect output.
Large images are slow to process.
Very high-resolution images (above 8000px) require more browser memory. Try reducing the input size first, or use a desktop browser instead of mobile for large files.
The output format is not what I expected.
Double-check the format selection before downloading. Some tools default to the input format — change it manually if you need a different output format.
