Question 1

How many images can I edit or convert at once in Forma?

Accepted Answer

Forma allows you to upload and process up to 20 images simultaneously in a single batch session. You can drag and drop multiple files at once or add more images at any time using the batch gallery strip.

Question 2

How does the 'Apply to All' feature work across images with different aspect ratios?

Accepted Answer

Forma uses a proportional bounding box calculation. When you apply a crop to all images, it normalizes relative coordinates (x/width, y/height, w/width, h/height) rather than fixed pixel dimensions. This ensures that landscape, portrait, and square images in your queue all receive an identically positioned proportional crop without distortion or clipping.

Question 3

What happens if an uploaded batch file exceeds the file size or resolution limit?

Accepted Answer

Forma automatically skips files that exceed safety limits (max 25 MB file size or 12,000 × 12,000 pixel dimensions) to prevent browser memory exhaustion. A subtle status badge immediately notifies you of the exact number of skipped files (e.g., '1 image(s) skipped (exceeded limit)'), while all valid images in your batch continue processing without interruption.

Question 4

Can I download all processed batch images as a single ZIP file?

Accepted Answer

Yes. In the Export panel, Forma provides an 'Export Batch as ZIP' option that packages all processed images into a single compressed ZIP archive. You can also download them sequentially if you prefer individual files.

Question 5

Can I edit individual images separately after adding them to a batch?

Accepted Answer

Yes. Simply click any thumbnail in the batch strip at the top of the editor. Each image maintains its own isolated settings for crop coordinates, pixel dimensions, color adjustments, rotation, and target format.

Question 6

Are my photos or images uploaded to remote servers or cloud storage?

Accepted Answer

No. Forma runs 100% locally in your browser using HTML5 Canvas, WebAssembly, and modern Web APIs. Your photos never leave your device, ensuring complete privacy for sensitive personal pictures, unreleased product photos, and confidential documents.

Question 7

How does on-device AI background removal work without a cloud server?

Accepted Answer

Forma executes a lightweight neural segmentation model directly inside your browser using WebAssembly. The model segments the foreground subject and creates an alpha mask in local memory with zero remote API calls.

Question 8

Does Forma require account creation, credits, or subscriptions?

Accepted Answer

No. Forma is completely free, open-access, and requires no account registration, API keys, subscription plans, or watermarks.

Question 9

What are the safe hardware and memory limits for browser processing?

Accepted Answer

To ensure your device remains smooth and responsive, Forma enforces a 25 MB single file limit, a 12,000 × 12,000 maximum pixel dimension, a 40,000,000 total pixel cap, and a 20-image maximum queue per batch session.

Question 10

How do I compare my edited image with the original photo?

Accepted Answer

Forma provides two instant comparison modes: the 'Split Slider' and the 'Hold for Before' button. Both tools display your genuine original photo with its original background and natural lighting, geometrically aligned with your current crop, rotation, and framing.

Question 11

How does the Split Slider comparison work?

Accepted Answer

Clicking 'Split Slider' opens an interactive split screen with a vertical divider. You can drag the divider left and right across the canvas to visually inspect subject cutouts, color grading, and exposure adjustments in real-time.

Question 12

Can I quickly toggle back to the original photo with a single click?

Accepted Answer

Yes. Click and hold the 'Hold for Before' button (featuring the eye icon) in either the canvas toolbar or the cutout controls to view the 100% unedited original image. Releasing the button instantly returns to your edited version.

Question 13

How do I batch resize images without losing sharpness or quality?

Accepted Answer

Always downscale from high-resolution masters rather than upscaling low-resolution files. Forma uses native bicubic canvas interpolation to cleanly blend pixel values, preserving fine edges and details.

Question 14

Which preset aspect ratios are supported for social media and web?

Accepted Answer

Forma includes instant presets for 1:1 (Square / Instagram Post), 4:5 (Portrait Feed), 3:4 (Standard Photo), 16:9 (Landscape / YouTube), 9:16 (Story / Reel / TikTok), and 2:1 (Twitter/X Banner), as well as a flexible Freeform crop tool.

Question 15

Does locking the aspect ratio prevent photo distortion?

Accepted Answer

Yes. When the aspect ratio lock is enabled, changing either the width or height input automatically recalculates the opposite dimension proportionally, preventing any horizontal or vertical image stretching.

Question 16

Which image formats can I import and export in bulk?

Accepted Answer

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).

Question 17

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

Accepted Answer

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.

Question 18

How does Forma measure estimated output file size before downloading?

Accepted Answer

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.

Question 19

How do I create transparent PNG or WebP images?

Accepted Answer

Use the Cutout Subject tool or Color Keying eraser to remove the background, and set the canvas background to transparent. When exported as PNG or WebP, the background will be 100% transparent alpha.
