What is Photo Filters?

Photo Filters applies preset filters to your images, including sepia, grayscale, warm, cool, vivid, and fade. Preview each filter instantly and download the result without uploading your photo to any server.

Sixteen presets are included: sepia, grayscale, warm, cool, vivid, fade, vintage, noir, dramatic, lomo, polaroid, matte, clarity, dusk, moody, and pastel. Each preset is a stack of CSS filters (sepia, saturation, contrast, brightness, hue rotation) and the intensity slider linearly interpolates between identity and the full effect. On top of any preset you can fine-tune brightness, contrast, saturation, warmth, hue, blur, sharpness, vignette, and film grain, then drag a split-screen divider over the preview to compare against the original at any ratio. Export as PNG, JPEG, or WebP at a quality you set, all at the photo's native resolution.

How to use

1. Upload an image from your device — it appears in the preview area immediately.
2. Browse the filter thumbnails and click any filter to see a live preview on your image.
3. Fine-tune the filter intensity with the slider, then download your filtered photo.

When to use

• Giving a phone snapshot a consistent editorial mood before posting to Instagram or a blog.
• Batch-styling product photos so an online shop's listings share a single visual identity.
• Reviving flat or underexposed shots with Clarity or Dramatic without learning a full photo editor.

Result

You have a landscape photo that looks flat. Apply the 'Warm' filter to add golden tones, set intensity to 75%, and download a richer-looking version.

FAQ

Are these filters destructive — can I undo or revert to the original photo?

Yes, the original stays in memory the whole session. Reset the fine-tune sliders and switch back to the Original preset to remove every effect at once. Only the file you download is final; the source image is never overwritten or sent to a server, so you can experiment freely.

What does the intensity slider actually do at 50% vs 100%?

At 100% you see the full preset values. At 50% each value is interpolated halfway toward its identity (sepia 1.0 becomes 0.5, contrast 1.45 becomes 1.225). It's a true linear blend, not just opacity stacking, so colours stay clean.

Why doesn't the downloaded image match the on-screen preview exactly?

The preview applies CSS filters live, plus a quick canvas pass for sharpness and vignette since those need real pixel work. The download bakes the exact same chain onto a 2D canvas at the original pixel dimensions, and the drag-to-compare divider lets you check parity against the untouched source. Colour rendering can differ slightly between display colour profiles, but the underlying maths is identical.

Will filters keep working on a 6000×4000 px DSLR photo or only on phone shots?

Up to 20 MB and any pixel size your device can decode. The canvas renders at the photo's native resolution, so DSLR files come out at full resolution — slower on older hardware, but the output quality matches the source.

Can I stack two filters, like applying Vintage and then Warm?

Not directly — only one preset is active at a time. Workaround: download the photo with the first filter at the intensity you want, re-upload the result, then apply the second filter. Each pass is non-destructive against the file you uploaded that round.
