SuperPixMia is a free, open-source, browser-based image toolkit. Resize, compress, remove backgrounds, and convert images between 9 formats — PNG, JPEG, WebP, AVIF, GIF, BMP, SVG, ICO, and TIFF — all processed 100% locally on your device.
Privacy first — Unlike most online image tools, SuperPixMia never uploads your images. Everything runs in your browser with Canvas API and WebAssembly. No accounts, no ads, no watermarks, no hidden costs.
Resize images to exact pixel dimensions with built-in presets — OG image 1200×630, Instagram 1080×1080, favicon 32×32 — or custom width and height. Lock the aspect ratio for distortion-free scaling. Free, no upload.
Reduce PNG, JPEG, WebP, and AVIF file size with a real-time quality slider. Watch the file size drop before you download, and compress up to 15 images in one batch — 100% in your browser, no upload, no watermark.
Remove image backgrounds with one click. AI segmentation runs entirely in your browser via WebAssembly — your photo never leaves your device. Preview the cutout against transparent, white, or black backgrounds, then download as a transparent PNG.
Convert images between PNG, JPEG, WebP, AVIF, GIF, BMP, SVG, ICO, and TIFF — online for free. Perfect for generating favicons, optimizing images for the web, or sharing to social media. Batch convert up to 15 images. No upload.
Remove watermarks, stamps, logos, and stray text from images online for free. Paint over the mark with a brush and the tool rebuilds the covered area from the surrounding pixels so it blends back into the background. Great for cleaning up screenshots, downloads, and photos you own. All processing happens in your browser — nothing is uploaded.
Click the upload area or drag and drop any PNG, JPEG, WebP, AVIF, GIF, BMP, SVG, ICO, or TIFF image into SuperPixMia.
Click the Compress tab in the toolbar. SuperPixMia automatically compresses the image as you adjust the quality slider between 1% and 100%.
Slide to your desired quality level. See the file size reduction in real time, then click Download to save your compressed image to your device.
