Comparison Table
Krita
open-sourceFree open-source digital painting application focused on illustration and concept art.
Krita’s assistant system provides perspective, ellipse, ruler, and vanishing-point guides that constrain freehand strokes.
Krita is an open source bitmap editor built around a painting-focused workspace and an extensive brush engine. It supports a layer based workflow with masks and filters, which is useful when finished artwork needs adjustable paint passes instead of flattened pixels. Configurable dockers help keep illustration and concept art tools organized during long sessions.
The animation workspace adds a timeline with keyframes, onion skins, and frame previewing for frame by frame raster animation. Python scripting supports custom dockers and task automation for repetitive illustration or animation steps. A tradeoff is that this painting and animation depth can feel heavier than basic retouching tools for users who only need quick cropping or color tweaks.
Krita fits artists who plan multi layer raster compositions and who want editable references per canvas. It also fits short shot rotoscoping or paint fixes when tracing or painting over imported frames is part of the workflow.
- +Brush engines cover pixel, color-smudge, bristle, particle, sketch, and MyPaint behaviors.
- +Python scripting API supports dockers, batch tasks, custom tools, and workspace automation.
- +Animation workspace provides timeline editing, onion skins, and frame management.
- +Wrap-around mode supports tileable texture painting with repeating canvas previews.
- –CMYK output and proofing workflows are less extensive than Photoshop's.
- –RAW development requires an external application because Krita is not a dedicated RAW processor.
- –Text layout tools remain basic for typography-heavy compositions.
- –Large documents can strain memory as brush size and layer count increase.

Referenced in the comparison table and product reviews above.
How to Choose the Right Bitmap Software
We separate bitmap software options by how they handle image quality at the pixel level, how well they preserve edits over time, and how consistently they move files between the tools you already use. The biggest differences show up in file format handling and nondestructive control, not in surface feature lists.
File format support and export control
Why it matters
Format support matters because bitmap work often travels between cameras, scanners, web assets, and internal review. Export control matters because teams need predictable output without hidden changes.
How to check
Import the same sample bitmap in a few common formats (including one with transparency) and confirm it keeps what you expect visually. Export using the tool’s export settings and verify the chosen output format preserves transparency and color appearance as shown in a side-by-side compare.
Nondestructive edit layers behavior
Why it matters
Nondestructive edit behavior helps when you revisit choices after feedback or when multiple versions share the same base image. It also reduces the risk that an adjustment becomes baked in and hard to undo cleanly.
How to check
Open a demo image and apply a tone or color change as an adjustment-type step, then turn that step off/on and reorder it if the UI allows. Save/export and confirm the change still updates correctly when you tweak the step after additional edits.
Transparency and color handling consistency
Why it matters
Bitmap projects frequently rely on transparency edges and consistent color appearance across outputs. If transparency or color handling differs between import and export, you end up fixing artifacts repeatedly.
How to check
Use a sample image with semi-transparent areas (hair, soft shadows) and export to at least two target formats. Compare edge quality and check whether transparency survives without unexpected halos or opaque regions.
Performance on large bitmaps
Why it matters
Bitmap software can feel slow when you push high-resolution images or frequent layer updates. Performance affects iteration speed during masking, painting, and filters.
How to check
In the demo, open a large bitmap (or a high-dimension export) and perform 2–3 iterative edits (paint/brush, a selection-based adjustment, then export). Time the responsiveness of brush strokes, selection edges, and filter previews.
Precision selection and edge cleanup tools
Why it matters
For many bitmap workflows, the limiting factor is not basic editing—it’s how precisely you can select, refine edges, and correct halos. Better tools reduce manual repainting and rework.
How to check
Run a selection on a test image with complex edges (strands, foliage, motion blur). Refine the edges using the tool’s built-in controls and then export to a transparent background to see whether edge artifacts remain.
Red flags
- Exports drop transparency or add halos you can’t control
- Adjustments become baked in so edits can’t be revisited cleanly
- Large-image edits lag or previews change unexpectedly
Fit by situation
- If you routinely exchange images across multiple tools and formats, prioritize File format support and export control.
- If you expect to revisit edits after review rounds, prioritize Nondestructive edit layers behavior.
- If you work with tricky cutouts and semi-transparent edges, prioritize Transparency and color handling consistency.
