Which image formats can I import and export in bulk?

Forma accepts PNG, JPG/JPEG, WebP, and non-animated GIF files. You can export individual or batch images to WebP (best for modern web compression), PNG (lossless with transparency), or JPG (universal compatibility with quality adjustment).

Why should I convert my JPG and PNG images to WebP?

Google WebP produces file sizes that are 25% to 35% smaller than JPEG and up to 50% smaller than PNG while maintaining comparable visual fidelity and supporting transparent backgrounds. Converting to WebP dramatically improves Google Core Web Vitals and website page speed.

How does Forma measure estimated output file size before downloading?

Unlike calculators that estimate file weights using arbitrary guesses, Forma performs real in-memory canvas blob encoding to display the exact byte size of your target export before you download it.

Understanding Digital Transparency

Direct Answer: Digital transparency is managed through an 8-bit Alpha channel that indicates how opaque or see-through each pixel is. JPEG does not support alpha channels and will automatically replace transparency with solid white. Always export transparent graphics as PNG or WebP.

No Fake Backgrounds: The checkerboard pattern clearly confirms transparent pixels.
Custom Padding: Add breathing space around your logo or product cutout.
PNG or WebP: Choose PNG for uncompressed precision or WebP for fast web delivery.

How to Remove Image Backgrounds to Transparent Alpha

Drop Your Graphic

Select or paste any JPG, PNG, or WebP up to 25MB. Files remain strictly inside local browser memory.

Activate AI Cutout

Tap 'Remove Background' to run local neural segmentation, or use 'Color Keying' for solid backgrounds.

Inspect on Checkerboard

Check real-time edge separation and contrast. Adjust tolerance sliders to eliminate unwanted fringes.

Export Transparent File

Download as 32-bit PNG or WebP with full alpha transparency. Avoid JPG which forces white backdrops.

Image Format	Alpha Channel Support	Compression Efficiency	Best Use Case
PNG (Portable Network Graphics)	Full 8-bit Alpha (256 opacity levels)	Lossless; larger file sizes	Logos, app icons, digital stickers, print
WebP (Google Web Picture)	Full 8-bit Alpha (lossy & lossless)	30-50% smaller than PNG	E-commerce websites, responsive web apps
JPEG / JPG	None (Replaces alpha with solid white)	Lossy photographic compression	Full-bleed photos without transparency
