Open Source Alternatives to Photopea
Image Transparency Checker is a browser-based alternative for users who need this focused result without installing a proprietary desktop app or entering a larger hosted workflow.
This research compares that workflow with Photopea while keeping the outbound source link at the bottom after the analysis.

TextFaker should provide a focused alpha inspection flow that decodes an uploaded image locally and reports transparent and semi-transparent pixel details.

Side-by-side open source alternative comparison
| Decision point | Image Transparency Checker | Photopea | Takeaway |
|---|---|---|---|
| Purpose | Our workflowAnswer whether the file contains transparency | Proprietary workflowEdit the image in a rich browser editor | TextFaker is better for quick QA. |
| File confidence | Our workflowChecks decoded pixels rather than relying on extension | Proprietary workflowLets users open and export many formats | A post-export checker catches real output behavior. |
| Report sharing | Our workflowOne copy-all result for handoff | Proprietary workflowEditor files and exports | TextFaker can support bug reports and client proof. |
| Repair workflow | Our workflowIdentifies the issue but does not edit it | Proprietary workflowCan be used to fix masks, layers, and exports | Use both when an asset fails the check. |
| Learning curve | Our workflowMinimal interface for one diagnostic task | Proprietary workflowPhotoshop-style interface with many tools | Users who only need a yes/no plus counts should not need an editor. |
| Transparency preview | Our workflowCheckerboard and solid backgrounds tied to numeric results | Proprietary workflowCanvas-based visual inspection | TextFaker should make result interpretation explicit. |
Detailed research
Why Choose TextFaker
TextFaker fits users who only need verification. A transparent image checker should avoid toolbars and editing decisions and instead return a direct result with counts, percentages, and a preview.
- Confirm whether a Photopea export retained alpha.
- Detect fully opaque images mislabeled as PNG.
- Quantify semi-transparent pixels around antialiased edges.
When Photopea Fits Better
Photopea is a better fit when the user needs to edit the image, preserve layered work, or re-export after fixing transparency.
- Use it for PSD-like layer workflows.
- Use it to change masks and backgrounds.
- Use it when the checker result shows a problem that needs repair.
Page Notes
The page should compare workflows, not claim TextFaker is an open-source Photopea. Use browser-based, local-first, and open-standards language.
Result Notes
The result should include a simple verdict such as fully opaque, contains fully transparent pixels, contains semi-transparent pixels, or mixed transparency.
- Include dimensions and total pixels.
- Include exact alpha count categories.
- Include copy-all output for the full report.
Research notes
- Photopea's official account documentation confirms free and premium account types.
- Photopea official documentation explains opening files in the browser editor workflow.
- Photopea is not fully open source according to its public repository notes, so avoid calling it open-source proprietary software comparison without nuance.
