Quick fixes and filters
Brighten a dark photo, add punch with contrast and saturation, warm or cool the colour, soften with a touch of blur,
or drop straight to black and white. One-tap presets — Vivid, Vintage, Cool, Warm, Fade, Mono — set a good starting
point you can fine-tune, and the preview updates instantly because it runs on the GPU.
Your original file is never touched; only the copy you download carries the changes, as a PNG or JPG. For a hand-drawn
look try Photo to Sketch; for a plain black-and-white conversion,
Black & White.
Frequently asked questions
What can I fix here?
Brighten an under-exposed photo, add punch with contrast and saturation, warm or cool the colour, soften with blur, or drop to black and white — all previewed live before you download.
Are the filters destructive?
Only the downloaded copy carries the changes; your original file is untouched. Presets just move the sliders, so you can fine-tune from there.
Is the photo uploaded?
No — the adjustments run on a canvas in your browser.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
