BMP → PNG
Separate submission, publishing, and editing needs so the same conversion lands cleanly.
Business docs, inspection reports, internal sharing, and lossless storage. Photo-like images can become large, so consider JPEG or WebP for final sharing.
Focus on resize and transparency checks more than a quality slider. Keep original dimensions for intermediate editing. With BMP, conversion is usually about size reduction and compatibility, not metadata.
For review, resize to the needed display size and keep the source separately. Keep the original BMP separately when it matters.
Route readout
A simple, often huge bitmap from older Windows tools or measurement software. Uncompressed size makes it poor for email attachments and web submissions.
PNG is lossless and preserves transparency and sharp edges for editing. Best for editors, documents, transparent assets, and avoiding extra generation loss.

Use this before saving to reduce failures around opening, readability, or file weight.
Check that lines/text remain sharp and file size is manageable.

No. Conversion runs in your browser and image files are not sent to a server.
Photo-like images can become large, so consider JPEG or WebP for final sharing. If the BMP source is part of an archive, keep the original after conversion. If a submission target specifies format, dimensions, or color requirements, check those first.
