Practical guide for better results

These recommendations are built for real publishing workflows: faster output, cleaner quality, and fewer avoidable edits.

Best use cases

  • Optimize hundreds of catalog photos before seasonal launches.
  • Prepare media libraries for CMS migrations.
  • Shrink old archives to save storage and CDN costs.

Step-by-step workflow

  1. Split very large jobs into smaller folders to review output quality quickly.
  2. Use one preset per folder so results stay consistent.
  3. Spot-check every 10-20 images before exporting all.

Quality tips

  • Separate portraits, product cutouts, and screenshots because each compresses differently.
  • Name output folders clearly (for example: "compressed-75").
  • Use moderate settings first; rerun only files still too large.

Mistakes to avoid

  • Uploading mixed image types with one aggressive profile.
  • Skipping sample review and discovering artifacts after publishing.
  • Replacing originals in bulk without version control.

FAQ context before you export

Batch workflows are best when consistency matters more than custom tuning per image. Save a predictable preset and repeat it for each campaign.

For edge cases like transparent logos or screenshots, process those in a dedicated pass with milder settings.

Frequently Asked Questions

How many images can I compress at once?

You can upload as many images as your browser memory allows. For best performance, we recommend batches of 50–100 images depending on their size.

Does batch compression affect image quality?

All compression involves some data reduction, but our settings help you find a sweet spot where file size drops significantly while images still look sharp.

Are my images uploaded to a server?

No. All compression happens directly in your browser. Your files never leave your device, so your images stay private.
