Easy Batch Customizer Pro

Easy Batch Customizer Pro does the tedious half of sprite work. Drop in a folder of PNGs — 20 or 500 — pick a colour, and the whole set is recoloured, palette-matched, outlined and exported while you watch. Everything updates live across the entire batch, not one file at a time.

It's built for the moment your art is finished and you still need six team colours, a PICO-8 version, a 2× sheet for the store page, and an atlas your engine can read.

How it works

See it working

See it in 15 seconds The whole loop — load, recolour, snap, variants, export.

One sprite, every colourway Define your colours once. The shading ladder survives, so variants read as hand-drawn.

The Variant Generator Six team colours in one click — 6 variants × 28 sprites = 168 files from one export.

Snap to any palette PICO-8, GameBoy, NES, Sweetie 16, Endesga — 34 built in, plus Lospec import.

Palette Radar Every colour in the batch, ranked by coverage. Click to select, right-click to lock.

31 tiling patterns Stripes, scales, camo, hex, marble — any two colours, with a “keep shading” slider.

Pattern library Live preview against your own sprite before you commit.

A whole batch, one pass Before and after: one re-tint plus a PICO-8 snap across every sprite at once.

Live across the batch Originals above, results below, updating as you drag — with real zoom for pixel art.

Before / after wipe Right-click any sprite: wipe slider, pixel grid, per-pixel colour readout.

Export the way your engine wants Sheets with Godot, Unity, Phaser or CSS atlases. Multi-scale in one run.

What it does

Palette Radar. Scans every loaded sprite and lists every colour in the batch, ranked by how much of the art it actually covers. Near-identical shades from anti-aliasing are folded into groups so the list stays readable. Click a swatch to select, ctrl-click to multi-select, right-click to lock it. Locked colours survive global effects and palette snapping — your outlines stay pure black while everything else shifts.

Recolouring, four ways.

• Colour mapping — source to replacement, with tolerance and an Auto button that picks a sensible one for your art.
• Re-tint — shift an entire sprite toward a target colour while preserving its shading ladder. This is the one that works on anti-aliased art, where a sprite can hold a different colour in nearly every pixel.
• Gradients — replace a colour with a multi-stop gradient in 7 directions, including radial and conic.
• Patterns — fill a colour with any of 31 built-in tiling textures.

Optional perceptual matching (OKLab) catches shading ramps that plain RGB tolerance walks straight past, and 14 blend modes apply per mapping.

Palettes.

• 34 built in — PICO-8, GameBoy, NES, CGA, ZX Spectrum, Sweetie 16, Endesga 32, Resurrect 64, 1-bit and more, from 2 to 56 colours.
• Import .gpl, .hex, .pal, .txt, .json, .css — or extract a palette straight out of any image.
• Lospec — paste a palette URL and it downloads.
• Auto-map — one click maps your batch onto the palette as editable rows.
• Build from your sprites — median-cut reduction in OKLab for a representative palette.
• Generate hue-shifted shading ramps and 8 harmony rules from a single colour.

Effects. Outline (outside, inside or centred; round or square; colour lockable) · drop shadow with offset, blur, spread and opacity · outer and inner glow · background removal with feather and de-spill · alpha cleanup for sprites that arrive fuzzy · hue, saturation, brightness, contrast, gamma, vibrance, warmth, posterise, grayscale, sepia, tint and invert · gradient map with shading preservation.

Pixel-art conversion. Downscale to a real pixel-art resolution with average, dominant-colour or nearest sampling, hard alpha (no muddy semi-transparent edges), adjustable alpha cut and optional colour merging. 13 dithering algorithms — ordered Bayer, blue noise, Floyd-Steinberg, Atkinson, Burkes, Sierra, Stucki, Jarvis — and dithering can target your active palette rather than a flat level quantisation.

Output. Trim, pad, power-of-two, fixed canvas, scale, flip, rotate · multi-scale export (1×, 2× and 4× in one run) · sprite sheets with uniform or tight packing · atlas metadata for Godot, Unity, Phaser/Pixi, JSON, CSS or plain text · animated GIF and WEBP · ZIP archives · per-variant folders · one-click export presets · batch renaming.

Recipes and automation

Your entire pipeline — every mapping, effect, palette and variant — saves to a single .ebcp recipe file. Re-apply it to any folder later, or run it headless from a build script:

EasyBatchCustomizerPro.exe --recipe knight.ebcp --in sprites/ --out build/ --variants --scales 1,2 --sheet 8 --atlas godot

Built to actually work in

• Live preview across the whole batch — originals above, results below, updating as you drag a slider.
• Small pixel art is scaled up by whole numbers with nearest-neighbour, so 16px sprites are actually visible. Fit, or fixed 1× to 16× zoom.
• A 13-stage pipeline that caches every stage — nudging a late slider only recomputes what comes after it.
• Right-click any sprite for a before/after wipe with a pixel grid and per-pixel colour readout.
• Sprite sheet splitter — fixed grid, rows and columns, or automatic island detection.
• Batch report — sizes, colour counts and soft-edge warnings before they reach your engine.
• Undo and redo across the entire pipeline, plus autosave and crash recovery.
• 29 rebindable shortcuts, 8 accent colours, compact density and adjustable UI scale.

Who it's for

Anyone shipping sprite sets rather than single sprites: indie devs who need team colours or rarity tiers, asset-pack authors producing palette variations, jam teams conforming borrowed art to one palette, and anyone turning high-resolution or generated art into consistent, game-ready pixel sprites.

Not a drawing program. It won't replace Aseprite — it does the batch work Aseprite isn't built for, on art you've already drawn.
