About jpg.now API

jpg.now API is a REST endpoint service for converting images and documents between over 100 formats programmatically. The API uses an asynchronous three-step workflow: submit a file via POST /api/v1/convert, poll the job status with GET /api/v1/jobs/{job_id}, and download the result from the completed job.
Conversions are charged in credits—1 credit for standard formats like JPG to PNG, and 2 credits for CPU-heavy formats like RAW files and PDF. The API supports quality adjustment, resizing, and offers both one-off credit purchases and monthly subscription plans. Premium and Premium Plus subscribers get API access at no credit cost.
Rate limits apply per minute, with separate monthly quotas. The service processes most conversions in under a second and supports all major image formats including JPG, PNG, WebP, PDF, HEIC, AVIF, and many others. Authentication uses API keys created on the dashboard.

FAQ
- How much do API conversions cost in credits?
- Standard conversions cost 1 credit each, including common formats like JPG to PNG, PNG to JPG, JPG to WebP, and compression. CPU-heavy formats cost 2 credits, including RAW camera files, PDF conversions, PSD files, TIFF, and vector rasterization.
- What happens if my API request is rejected?
- Rejected requests such as invalid API keys, rate limit violations, or unknown converters return error codes but do not consume credits. If a credit is charged but the job fails to queue, it is refunded automatically.
- Can API usage exceed my quota without additional charges?
- No. Over-quota requests are refused outright and return a 402 error instead of being billed. There is no overage charge, so a runaway script cannot produce surprise invoices.
- Is it really free?
- Yes — all core image conversion tools are free with no account required and no credit card ever needed. The free tier and Free Account plan are free forever.
- What happens to my files?
- Files uploaded as a guest are automatically deleted within 24 hours. Free account files are deleted after 7 days, Premium after 365 days, and Premium Plus files are stored indefinitely. We never share or index uploaded content.
