How do I apply a filter to an image with img-tools?

Open the Image Filters page and load your image by dragging it in, clicking to browse, or pasting (JPEG, PNG, WebP, and AVIF are supported). Pick a preset such as Grayscale, Sepia, Invert, or Duotone, then fine-tune the brightness, contrast, and saturation sliders while the preview updates live. Click Export to download as JPEG, PNG, or WebP — it is free, runs entirely in your browser via the Canvas API, and your image is never uploaded.

Are images uploaded to a server?

No. Filters and adjustments run entirely in your browser; images never leave your device.

Which filters are included?

Grayscale, Sepia, Invert, and a blue Duotone preset, plus brightness, contrast, and saturation sliders you can combine.

Can I combine a preset with adjustments?

Yes. The preset is applied first, then your brightness/contrast/saturation tweaks on top.

Is the Image Filters & Effects tool free?

Yes — applying filters such as Grayscale, Sepia, Invert, Duotone, and adjusting brightness, contrast, or saturation is completely free, forever. No account, no sign-up, and no limit on how many images you filter. Everything is processed in your browser using the Canvas API; your images are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. The tool uses the Canvas API and needs no server connection.

What formats are supported?

Input: JPEG, PNG, WebP, AVIF. Output: JPEG, PNG, WebP.
