Three steps. Any number of photos.

Bulk photo editing without the busywork: no exporting one shot at a time, no copying settings by hand. Jumpman treats a batch like a single image, until you want it not to.

  1. Collect

    Drop photos into a collection like “Spring Pink”. They stay on your device. Nothing is uploaded, ever.

  2. Select

    Tap the shots you want, or let smart selection grab every photo from the same moment, scene or palette.

  3. Edit together

    Every slider, layer and preset lands on the whole selection. Flip to Individual to fine-tune one photo without breaking the set.

Batch editing

The core of Jumpman: a batch that behaves like a single photo, until you want it not to.

One global edit, applied to all ten photos.

  • Collections

    Available

    Photos live in collections like “Spring Pink”. Multi-select the shots you want, tap “Edit these images”, and they open as one batch.

  • Global edit with a summary bar

    Available

    Set brightness, exposure, highlights, shadows and saturation once for the whole batch. A summary bar keeps every change in view.

  • Global or Individual

    Available

    One toggle switches between editing the batch and fine-tuning a single photo. A dot indicator flips you through the set, photo by photo.

  • Layers

    Available

    Stack Adjust, LUT, Curves, HSL and Split toning layers. Add, edit, delete and reorder them, and give each its own opacity.

  • A panel made for precision

    Available

    A dial-style slider for fine moves, a live histogram, and a before/after compare that is always one tap away.

Pro workflow

The tools a working photographer reaches for, rebuilt for sets of photos instead of single frames.

A side-by-side before-and-after grid of the whole batch in the Spring Pink look.
Check the whole batch before and after.

  • Presets and recipes

    Available

    Save any edit as a preset, then share it as a link or a file.

  • Copy and paste edits

    Available

    Copy an edit from one photo and paste it onto any selection.

  • Auto-match exposure and white balance

    Available

    Even out a set shot under mixed lighting, so the window-lit and lamp-lit frames finally agree.

  • Smart selection

    Available

    Select by similarity, by time range or moment, by scene type, or by color palette.

  • Per-photo override indicator

    Available

    See at a glance which photos differ from the batch, and reset any of them with one tap.

  • Batch before/after grid

    Available

    Review the whole set before and after, side by side.

  • Masking and local adjustments

    Available

    Linear, radial, luminance and color-range masks, plus heuristic sky and subject masks that adapt to each photo in the batch.

  • Bulk crop and aspect ratios

    Available

    Crop everything to 1:1, 4:5, 3:4, 9:16 and more, then reposition the framing image by image.

  • Batch export

    Available

    Resize and export to JPEG, PNG, WebP or AVIF with quality control, watermarks and filename patterns, as a ZIP or straight to the share sheet.

  • Non-destructive history

    Available

    Per-batch undo and redo, and a one-step revert of the whole collection to the originals.

  • Advanced color

    Available

    Curves, 8-band HSL, split toning and 15 built-in LUTs with live previews. Import and export .cube files.

  • RAW files and Lightroom XMP

    Available

    Opens RAW files through their embedded full-size previews (DNG, CR2/CR3, NEF, ARW, RAF, ORF, RW2 and more). Imports and exports XMP compatible with Lightroom, and imports Capture One styles.

Only in Jumpman.

Ideas you won’t find in other editors, built for the moment you have forty photos and one evening.

  • Reference-match

    Available

    Pick a hero photo and the rest of the batch matches its tone and color.

  • Edit from a sample image

    Available

    Drop in any photo you love and get a LUT that approximates its look.

    Available

    See how cohesive the set really is, then press Harmonize to pull the outliers into line.

    Exposure +0.6 means “bring everything to this brightness”, not “add 0.6 to everything”, so dark and bright shots land in the same place.

    Available

    Type “warmer, softer highlights, slightly faded” and get real slider moves. It runs fully offline.

  • Scene-aware auto edit

    Send a client a small review file. They comment, approve and suggest edits that show up as proposed layers. No server needed.
