Photo Enhancer: Fix Many Photos at Once

Brighten, balance and sharpen many photos at once with one-tap Auto, Vivid, Portrait, Low light or Document looks, then fine-tune. Runs in your browser, no upload.

JPG, PNG, WebP or HEIC, as many as you like
Enhanced on this device. Choose several photos: Auto fixes brightness, colour cast and softness in each one, and you can fine-tune all of them together or one at a time before saving.

Better photos in one tap, for the whole batch

Most photos that look flat, grey or yellow are not bad photos: the camera simply guessed the exposure or the light colour slightly wrong. A few measured corrections fix them, and because the corrections are measured from each photo, the same Auto setting works across a whole batch: the dark one gets brighter, the bluish one warmer, the soft one crisper.

  1. Choose or drop all your photos at once.
  2. Check the preview: drag the slider across to compare before and after.
  3. Pick a preset or fine-tune with the sliders, for all photos or just the selected one.
  4. Press Enhance and download each photo, or all of them as a ZIP.

What each correction does

  • Auto levels finds the darkest and brightest real tones in each colour channel and spreads them across the full range, so a hazy photo gets true blacks and clean whites.
  • White balance assumes the scene averages out to grey and corrects toward that, but only part of the way, so a sunset keeps its warmth while a photo under tube lights loses its green.
  • Shadows and highlights are a gentle curve: faces in shade come up, skies keep their detail.
  • Vibrance adds colour mostly where there is little, so grass greens up without skin turning orange.
  • Sharpening is an unsharp mask on brightness only (no colour fringes), sized to the photo, so a phone photo and a thumbnail both get the right amount.

Frequently asked questions

What does Auto actually change?

Five things, measured from each photo rather than applied blindly. It stretches the darkest and brightest tones to use the full range (ignoring the extreme half percent, so one bright lamp does not decide it), pulls a colour cast toward neutral, lifts shadows and holds back bright skies, adds a little colour to dull areas without oversaturating skin, and sharpens fine detail by an amount that suits the photo's size. Dark photos also get a light noise smoothing.

Are my photos uploaded?

No. Every photo is opened, enhanced and saved by your own browser. The heavy pixel work runs in a background worker on your device so the page stays responsive; nothing is sent to a server, and the page works offline once loaded.

Can I give one photo a different look from the rest?

Yes. Select the photo, switch "Changes apply to" to This photo only, and choose a preset or move the sliders. That photo keeps its own look (it is marked "Own look"); every other photo follows the shared settings. "Use the shared settings" puts it back.

Which preset should I use?

Auto suits most photos. Vivid adds punch to landscapes and food. Natural is the gentlest correction. Portrait keeps skin tones soft and warm. Low light lifts dark indoor or night photos and smooths the grain. Document whitens paper and sharpens text, for photos of notes and receipts; for a properly flattened scan, use the document scanner.

Will it lose quality or change the size of my photos?

The pixel size stays the same. JPG and WebP are saved at the quality you choose (High is 90%, visually lossless for photos); PNG is lossless. Camera details such as GPS location are not copied into the new files.

Does it work with iPhone HEIC photos?

Yes. HEIC photos are decoded on your device and saved as JPG (or the format you choose), with the correct orientation applied.
