A private image toolkit, not just a watermark remover

Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.

Lossless watermark removal

Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.

Crop & resize

Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.

Convert & compress

Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.

100% private

Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.

Filters are applied at full resolution with no extra compression. Export quality is controlled separately when you download as PNG, JPG or WebP.

Free online photo filters

PixKit gives you a row of one-click photo filters that apply instantly to your image — no sliders to fiddle with and no waiting. Pick grayscale for a clean black-and-white look, sepia or vintage for a warm nostalgic tone, invert for a negative effect, warm/cool to shift the white balance, or high-contrast and vibrant to make colors pop.

Instant and reversible

Each preset is applied with hardware-accelerated canvas filters, so the result appears immediately even on large images. Every filter is fully undoable, so you can stack, compare and revert effects freely until you get exactly the look you want.

Private by design

Filters run entirely in your browser — your photos are never uploaded, stored, or seen by anyone. It is fast, unlimited and works offline, which makes it safe for client work and personal photos alike.
