FAQs
How do the crop coordinates (X, Y, Width, Height) work?
X and Y define the top-left starting corner of your crop frame in pixels, while Width and Height specify the horizontal and vertical span of the cropped box.
Can I crop to exact social media aspect ratios?
Yes. Pixelora includes instant presets for 1:1 Square (Instagram Posts/Avatars), 4:3 (Photography), 16:9 (YouTube & Presentations), and 9:16 (TikTok & Reels/Stories).
Does cropping reduce the sharpness of the remaining image area?
No. Pixelora extracts the exact raw pixels from your source image within the defined bounding rectangle without downsampling or applying lossy filters.
What formats can I crop?
Pixelora supports cropping JPEG, PNG, WebP, and BMP images, exporting to your chosen format.
Is my uploaded photo kept private?
Absolutely. All cropping calculations and rendering occur locally in your browser memory with zero server uploads.
