Will image quality be reduced when converting PBM to PNG?

You control the quality. By default we use a high-quality setting. If PNG is lossy, you can adjust the quality level before converting.

Is my PBM file kept private?

Images are permanently deleted from our servers right after your download.

Can I batch convert multiple PBM files to PNG?

Yes. Upload up to 10 images at once on the free plan.

Does the converter support transparent backgrounds?

Yes, if PNG supports transparency (PNG, WEBP). For formats like JPG, the background defaults to white.

About PBM and PNG

.pbmPortable Bitmap

image/x-portable-bitmap

Monochrome image format in the Netpbm family.

.pngPortable Network Graphics

image/png

PNG is a raster-graphics file-format that supports lossless data compression. It supports palette-based images, grayscale, and full-color non-palette-based RGB or RGBA images. Its most notable feature is support for transparency (alpha channel).

Conversion Notes

Image conversion from PBM to PNG preserves colour information and dimensions. If PNG uses lossy compression (such as JPEG), compression artefacts appear at lower quality settings — use quality 85+ to minimise visible loss. Transparency (alpha channel) is preserved in formats that support it; if the target format does not support transparency, transparent areas are filled with white by default.
