Shrink JPG, PNG and WebP to a target file size without uploading. PixKit finds the best quality that fits your KB budget and shows the result before you download.
Add one or many — PNG, JPG & WebP. Or paste with ⌘/Ctrl + V
Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.
Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.
Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.
Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.
Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.
No tutorials, no settings — drop, edit, export.
Drag in, paste, or pick a file. The Gemini watermark is removed automatically on load — no settings.
Crop, resize, rotate, adjust, remove the background or redact — with full undo/redo and a Before/After view.
Download or copy as PNG, JPG, WebP, AVIF or PDF — or batch-export a whole folder as a ZIP. Free, unlimited, watermark-free.
Everything about compressing images with PixKit.
PixKit compresses images to a precise file size, free and fully in your browser. Enter a target in kilobytes and it binary-searches the optimal quality so your image is as sharp as possible while staying under the limit — ideal for email attachments, faster websites, and upload caps.
Choose WebP or JPG for the smallest sizes with a quality slider, or keep PNG for lossless graphics. The live size estimate updates as you change settings.
No uploads, no queue, no limits. Compression happens locally, so even large images process in seconds and your files never leave your device.
One private editor, a tool for every job — all 100% local, no upload.
