Resources
Reference material for working with images. We publish a competitor or marketplace figure only when we have read it on that vendor's own page, and every number links back to its source. Where we could not confirm something, the table says so rather than guessing.

Choosing a tool
Pricing, limits and terms, with every competitor figure linked to the vendor's own page.
Background remover pricing comparison
What each tool costs, what the free tier includes, and where published figures could not be verified.
Free background remover limits
Which free tiers return full-resolution files and which hand back a degraded preview.
How image editing credits work
Converting a credit allowance into a real cost per image, and the terms that change what a credit is worth.

Three different things get marketed as free. Five questions reveal which one you are being offered.
Watermarks and output restrictions
The four ways free tools restrict output, and a three-minute check before you build a workflow.
Choosing a background removal API
A vendor-neutral checklist: rate limits, resolution caps, failure billing, latency and licensing.
Background removal
How cutouts work, why they fail, and what to change at capture.
What causes background removal artifacts
Halos, jagged edges and chewed hair, each matched to its cause and fix.
Difficult subjects
Hair, glass, chrome, white on white and motion blur, with the capture-side fix for each.
Alpha channels and matting
Why the difference between a binary mask and a true matte decides cutout quality.
High-resolution specs
Output resolution caps per tool, and why a background remover can silently shrink your image.
Ecommerce and product photography
Specs, workflow and quality control for catalogue images.
Product image requirements by marketplace
Dimensions, file size, formats and background rules, with links to each marketplace's docs.
Product photo QA checklist
What to verify before uploading, ordered by how expensive each defect is to catch late.
Ghost mannequin apparel photography
The two-shot method, and why fabric is harder to cut out than rigid products.
Image fundamentals
The technical reference behind everything above.
Transparent background file formats
Which formats carry an alpha channel and which silently discard it.
Resolution, DPI and PPI
Why changing DPI does not change quality, and the pixels each output actually needs.

Common ratios, what a crop actually costs, and how to shoot once for several formats.
Lossy vs lossless compression
Why re-saving a JPEG degrades it, and how to build a pipeline that compresses once.
sRGB vs Adobe RGB vs Display P3
Why images look washed out online, and which space to use for each output.
Image metadata and editing
What EXIF, IPTC and XMP store, what survives upload, and the one block never to strip.

Sizing, format choice and delivery, ordered by payoff relative to effort.
When AI upscaling cannot help
Where reconstructed detail is worse than none: text, faces, logos and evidence.
