WFastPic

An open source tribute to Picasa, for Windows: pick and fix hundreds of photos fast.

Open the vacation folder, press Space to keep the good shots and Delete to reject the rest, fix a few in one click and export. Built for large HEIC collections from iPhones, drones and cameras — all from the keyboard, without ever waiting.

WFastPic grid: selected photos outlined in yellow, star ratings and the folders panel grouped by year — The grid: `Space` keeps a photo, bursts are grouped, folders are listed by year like in Picasa.

WFastPic editor: edits panel on the left, photo details and mini-map on the right, thumbnail strip below — The editor: crop, straighten, “I'm Feeling Lucky”, details, place and shooting data.

Why it exists

Google stopped developing Picasa in 2016, and it cannot read the HEIC photos phones take today.

What I missed most about Picasa was being able to go through all the photos of a vacation, pick the good ones on the fly, improve them in a click and then export them. No other program does it so comfortably and so fast. WFastPic is my way of getting that program back, on today's Windows and with today's photos. — Walter, author of WFastPic

It is not Lightroom and not a file manager: it is the tool for going from 1,300 shots to the 80 photos worth keeping, in as few gestures as possible.

What it does

Pick

Fast grid even with thousands of photos, in shooting order, optionally split by day.
Space selects, Delete rejects, 0–5 stars.
Bursts detected automatically: Shift+Space keeps this one and rejects the rest.
Automatic quality rating that flags blurry and dark shots — always kept separate from yours.

Fix

Crop with suggested crops that never cut faces; straighten; rotate and flip.
“I'm Feeling Lucky”, fill light, highlights, shadows, temperature.
Non-destructive: the original file is never touched.

Find again

Folders grouped by year, like Picasa.
Photo map with place names, location fixable by hand.
People: on-device face recognition, names shared across folders.
Live Photos and DJI drone data recognized.

Export

JPEG at original or reduced size, chosen quality.
Watermark and tags.
Shooting date and GPS kept — or removed, if you prefer.

From Picasa to WFastPic

If you used Picasa, you already know how it works.

In Picasa	In WFastPic
Folders grouped by year	Folder panel by year, with photo count and period
Stars and “kept” photos	`Space` selects, `0`–`5` stars, `Delete` rejects (never an irreversible delete)

Crop and straighten	Crop with ratios and suggested crops, straightening together with cropping
People (named faces)	Face recognition on your PC, names shared across folders
Photos on a map	Photo map and place names
Export	Resized JPEGs, watermark, tags, date and GPS preserved
—	Bursts, HEIC photos, Live Photos, DJI drone data

Your photos stay yours

Originals untouched

Selections, stars and edits live in a hidden .wfastpic folder next to the photos.

Everything on your PC

No account, no cloud, no telemetry. Face recognition runs locally.

Only what you choose

Map tiles, place names and the update check can all be turned off. Privacy note

Questions

Is WFastPic free?

Yes. It is open source under the MIT license, with no ads, no account and no paid version.

Does it open HEIC photos from iPhone?

Yes, it is built for them. Windows needs the HEIF and HEVC extensions, which are usually already installed; if photos do not open, get them from the Microsoft Store.

Does it change my original photos?

Never. Edits are saved as a recipe next to the photos and applied when you view or export. Rejects go to the Recycle Bin (with confirmation) or to a separate folder.

Which languages and systems?

English and Italian. Windows 10 (1809 or later) and Windows 11.
