About Batch and Interactive Editor

How to use Interactive Editor

  1. Choose Interactive Editor to open batch originals on separate pages, or choose images directly in the editor.
  2. Adjust brightness, contrast and colour on the selected photo. Use Pages to move between photos; each page keeps its own edits.
  3. Choose a format, use Export image, then download the result. Export all pages (ZIP) saves every page. Save project keeps layers editable.

Switching to the editor opens originals on separate pages. Each page is edited individually, with no Apply to all pages. Batch settings and results stay separate from editor edits. Switching back restores each mode's session until reload.

Export one editor page or all pages as a ZIP. Save project keeps editable layers and embedded original image bytes, including original metadata. Exported images are rebuilt from pixels and do not retain that metadata.

How it works

How to adjust brightness and colour of an image

  1. Add up to 20 images — JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF. They stay in your browser.
  2. In Batch, start with Auto fix or a Look, then fine-tune Brightness, Contrast, Saturation and Warmth. More adjustments adds highlights, shadows, whites, blacks, vibrance, tint, sharpen, clarity, vignette and a Duotone or Replace colour effect. The preview updates as you drag; press and hold Hold for original to compare.
  3. Choose Interactive Editor to open the original photos on separate pages with Adjust open. Edit each page individually and export one image or all pages as a ZIP. Return to Batch to resume its settings and results. Each mode retains its session until reload.
  4. Add Resize, Format or Compress if needed. Adjust, compare the result with the original, then download each image or a ZIP.
Frequently asked questions

Useful details

7 answers
What does Auto fix do?

It looks at each photo's own darkest and brightest tones, ignores the extreme 0.5% at either end, and stretches what is left to the full range from black to white. Dull, hazy or underexposed shots get clearer contrast. A photo that already uses the full range, or one that is almost a single tone, is left as it is.

How do I brighten a dark photo without washing it out?

Move Brightness to the right. It brightens shadows and mid-tones on a curve that keeps pure white white, so highlights do not blow out the way a flat lift would. Add a little Contrast afterwards if the photo looks flat.

Do all images get the same adjustment?

In Batch, the sliders and look apply to every image; Auto fix is measured per photo. In Interactive Editor, each photo has a separate page and its own adjustments. There is no Apply to all pages. Switching modes opens originals, without carrying over adjustments or results. Batch settings and editor edits remain separate until reload.

Can I sharpen photos or add a Duotone look to a batch?

Yes. Open More adjustments: Sharpen and Clarity add crispness, Vignette darkens or lightens the edges, and Colour effect applies a Duotone (Ink, Plum, Ocean, Amber or your own two colours) or replaces one colour with another in every image. They use the same pixel processing as Interactive Editor and work in workflows too.

Can I turn a photo black and white here?

Set Saturation to −100 for gray tones with your other adjustments. For pure two-colour black and white with a threshold, use Grayscale Image.

Can I use this in a workflow?

Yes. Add Adjust Image to an image workflow or a step-by-step workflow, set Auto fix, the sliders and any More adjustments, then chain it with Resize, Compress, Add Border, Image to PDF or other compatible steps and save the workflow settings for later.

Are my photos uploaded?

No. Adjusting, previewing and comparing happen in your browser. Keep the tab open until you download your images; reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.
