Upscale slideshow images 4x with no watermark — sharper photos for crisp TikTok carousels.
Upload a JPG or PNG and the model does a detail-preserving 4x upscale rather than a simple resize: it reconstructs edges and texture instead of just stretching existing pixels, which is why the output holds up at full-bleed slideshow size instead of looking soft. The result is capped at 4000px on the long edge, which covers a full-screen 9:16 or 4:5 slide with headroom.
Drop a JPG or PNG up to 10MB.
Detail-preserving upscale to 4x resolution.
No watermark, ready for your slideshow.
It replaces the plugin-heavy workarounds in Photoshop or GIMP and the paid tools that gate the same result behind a subscription. It's the right call for a sourced Pinterest image that's a little undersized for a full slide. It won't fix a heavily compressed thumbnail, though: upscaling sharpens detail that's already there, it doesn't recover detail a JPEG already threw away, so start from the highest-resolution version of an image you can find before you upscale it.
Up to 4x, capped at 4000px on the long edge.
None — the output is clean.
JPG, PNG, and WebP in and out.
