Common Use Cases & Tips
For Blog Images
A 1600px long edge usually keeps good visual quality while improving page speed.
For Email Attachments
Try long edge 1280px and quality 75 to reduce attachment size and avoid send failures.
Fine-Tune Quality
If quality matters, test in this order: 80 -> 75 -> 70 and compare each result.
When PNG Stays Large
PNG reacts less to quality sliders. Resizing or converting to JPEG/WebP is often more effective.
Speed Up Repeated Use
Enable “Remember these settings” to start with the same setup next time.
FAQ
Are images uploaded?
No. Images are processed locally in your browser and are never sent to a server.
Will image quality drop?
You can adjust quality while checking the preview. Save with the quality/size balance you need.
Can I process multiple images?
Yes. You can select multiple images and process them in batch. ZIP download is coming soon.
Why does PNG compression sometimes seem weak?
PNG is lossless, so size reduction often comes more from resizing or converting to JPEG/WebP.
Can I use HEIC (iPhone images)?
Support depends on browser. If HEIC is not supported, convert it to JPEG/PNG first.
