Batch Photo Resizer for Wedding Galleries

Every wedding photographer delivers the client gallery at full resolution and then immediately needs three or four other versions. Smaller for the blog post that Google reads. Different dimensions for Instagram feed grid. Tight squares for the studio portfolio. Long-edge 1200 for email previews. Doing that in Lightroom means four different export presets, four separate batch exports, and four folders to keep organized. That alone eats a full hour after every shoot, multiplied across thirty weddings a season.

Most photographers end up just resizing a handful by hand and calling it done, which means most of the wedding never gets properly published anywhere beyond the full gallery. The blog post gets three photos instead of fifteen. The Instagram carousel gets two shots instead of ten. The studio portfolio slowly goes stale because refreshing it takes real time. This tool fixes that by handling the batch resize step in your browser, in parallel, with the presets the wedding industry actually uses.

The resizing algorithm preserves the tonal gradation that makes wedding photos readable. A reception shot lit by candles and fairy lights has narrow shadow detail that generic resizers crush. This path uses smarter downscaling that keeps the mood of the shot intact at smaller sizes. A 3000-pixel image at 1200-pixel output still looks like your work, not like somebody ran it through an algorithm that does not understand what a wedding feels like at night.

For a wedding blog post, the standard is 1800 pixels on the longest edge. This is large enough for retina-quality display on a 27-inch iMac, small enough to keep page-load times under two seconds for Google PageSpeed, and sharp enough that the photo reads clearly even when the post gets pinned to Pinterest and reshared at Pinterest's preview size.

For Instagram feed grid posts, 1080 by 1350 (the 4:5 portrait ratio) is what the Instagram algorithm actually serves. Posts published at 1080 by 1080 get downgraded to Instagram's internal 1080 but lose vertical real estate in the feed. The tool can resize the batch to 4:5 with a smart crop that preserves the couple when the original was shot landscape or 3:2.

For client email previews, 1200 pixels on longest edge is the sweet spot. Large enough that the client can see detail on a phone screen, small enough that Gmail and Outlook do not strip it out as an oversized attachment. For long-range couples traveling in areas with slower internet, these previews load quickly and the client does not get frustrated trying to see their own photos.
