❓ FAQ

Q: What image formats are supported?

Input: JPG, PNG, HEIC
Output: JPG, PNG, HEIC
All three formats can be converted to any other format freely.

Q: What resolutions are supported?

Custom resolution: 1×1 to 16000×16000 pixels
Max output: 16000×16000 pixels
Covers everything from social media thumbnails to professional print.

Q: What are the two scaling modes?

Fill: Crops the image to exactly fill the target dimensions. Best for social media covers, banners, and e-commerce product images where a specific aspect ratio is required.

Aspect Fit: Scales the image to fit within the target dimensions while preserving the original aspect ratio. Best for product display, portfolios, and any case where the full image must be visible.

Q: How fast is the processing?

With Metal GPU acceleration enabled (automatic on all modern Macs):

Export 10 × 4K images: under 3 seconds
1K → 4K upscale: ~50ms per image
Batch 10,000 images: UI stays fully responsive throughout

Speed depends on your Mac's GPU, image size, and output resolution.

Q: How do I convert HEIC photos from iPhone to JPG?

Drag your HEIC photos (or the folder containing them) into the app
Click "Select All" or choose specific photos
Set output format to JPG and adjust quality as needed
Click Export and choose your output folder

All HEIC files will be converted to JPG, ready to share with anyone on any platform.

Q: How do I batch process an entire folder?

Simply drag the entire folder into the app's album area. The app will automatically scan all subfolders recursively and import every supported image. You can then select all and export in one go.

Q: What output quality should I choose?

90–100%: Professional photography, print, archiving
70–85%: Web use, social media — good balance of quality and file size
50–65%: Email attachments, messaging — smaller files
10–45%: Thumbnails, previews — smallest file size

Note: PNG format is always lossless regardless of the quality setting.
