Adjust image & filters

Tune brightness, contrast, saturation and warmth, or apply one-tap filters — live, in your browser.

Adjusted on your device — nothing is uploaded

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Adjust Image

  1. Drop an image.
  2. Move the sliders or tap a preset — the preview updates live.
  3. Download PNG or JPG.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

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.

Your files never leave your device

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.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
