Sharpening & upscaling

Fix blurry listing photos without reshooting

A photo can come out soft for several different reasons — low light forcing a slow shutter, digital zoom stretching pixels, or a photo that's been through several rounds of text-message or email compression. voxelyo fixes the most common causes automatically, without you needing to know which one caused the problem.

The three different causes of a soft or blurry photo

What voxelyo actually does to fix it

Auto mode runs denoising, sharpening, and upscaling together on every uploaded photo — it doesn't require you to diagnose which of the three problems above is causing the issue. The processing pipeline resizes the image up to a sharper target resolution (capped at a sensible ceiling so files stay a reasonable size), applies noise reduction tuned to avoid smearing fine detail, and sharpens edges back up. This is a deterministic image-processing transform, not a generative model — it runs in well under a second per photo.

Auto correction vs. AI Enhance: which one to use

Auto mode covers the large majority of blurry-photo cases — noise, low resolution, and compression artifacts all respond well to the deterministic denoise/sharpen/upscale pipeline, and it processes in well under a second with no queue. For a photo that's still soft after Auto mode, or one with genuinely heavy noise from a very dark room, AI Enhance runs a full generative model pass instead of a fixed transform. It takes roughly a minute per photo rather than being near-instant, so it's worth reaching for on the small number of photos where the fixed pipeline isn't enough — not as the default for every upload.

Quick checks before you upload

A few habits reduce how much correction a photo needs in the first place, even though voxelyo doesn't require any of them. Wiping the phone's camera lens before shooting removes the smudge-related softness that no amount of sharpening can fully undo. Avoiding digital zoom — walking closer instead of pinching to zoom — keeps the source resolution higher, which gives the upscaling step more real detail to work with rather than artificially stretched pixels. And re-exporting a photo at its original resolution rather than a screenshot of it (screenshots re-compress and often downscale) avoids stacking a second round of compression artifacts on top of the first. None of this is required before uploading — Auto mode handles photos straight from the camera roll — but it does mean less correction is needed and more of the original detail survives the process.

What this can't fix

Being honest about the limits: if a photo is blurry because of camera shake or a subject that moved during the shot (motion blur), sharpening can improve the appearance somewhat but can't fully recover detail that was never captured. Severely out-of-focus photos — where the camera missed focus entirely — have a similar limit. For a photo that's genuinely unusable due to motion blur or missed focus, the most reliable fix is still reshooting it. voxelyo works best on photos that are soft or grainy for the reasons above, not photos with severe camera-shake blur.
