Comparador Antes / Depois
Two photos. One drag. A comparison people actually trust.
Add your two photos
Same subject and framing works best - see the tip below.
info Tip: use two photos of the same subject and framing (same angle, same crop) for the cleanest comparison.
Sobre esta ferramenta
Upload a before photo and an after photo, then drag a divider across the frame to compare them - the same interaction used by renovation, fitness, skincare and photo-editing accounts to show a transformation without posting two separate images. The divider is keyboard accessible as well as touch and mouse draggable, both photos are cover-cropped into a locked aspect ratio so the comparison stays visually aligned even when the source photos differ in size, and the finished comparison exports either as a single split image or as a side-by-side image. Everything happens in your browser.

- Drag the dividerClick or touch anywhere in the frame and drag, or tab to the handle and use the arrow keys.

- ExportDownload the current split as one flattened image, or download both photos side by side.
Por que usar
- Keyboard-accessible divider, not just a mouse-drag gimmick - tab to it and use arrow keys.
- Aspect lock keeps both photos aligned in the same frame even when their original dimensions differ.
- Two distinct export modes: a flattened split image at the current divider position, and a side-by-side image.
- Editable Before/After labels baked into the exported image.
- Runs entirely client-side - neither photo is ever uploaded.
Usos comuns
- Before/after renovation, cleaning or restoration photos.
- Fitness or physical transformation progress comparisons.
- Photo-editing or retouching comparisons for a portfolio.
- Product comparisons where a visual side-by-side communicates a change better than text.
Dicas para melhores resultados
- Use two photos of the same subject, angle and framing for the cleanest, most convincing comparison.
- Lock the aspect ratio if your two photos were shot at different crops or orientations.
- Use Swap if you uploaded the photos in the wrong order rather than re-uploading.
Erros a evitar
- Comparing two photos shot from noticeably different angles or distances - the slider cannot correct for that, only the crop.
- Leaving the aspect ratio on Auto when the two photos have very different proportions, which can distort the framing.
