Como o swapfile.io funciona

O conversor e o limpador de metadados rodam inteiramente no seu navegador, usando a File API e canvas. Seu arquivo é lido para a memória no seu dispositivo, processado ali e baixado dali. Para formatos que um navegador não consegue decodificar (como HEIC fora do Safari), um pipeline no servidor está a caminho; esses trabalhos serão excluídos do armazenamento em até uma hora.

Fluxo de dados

API

Convert files from your own code with a REST API. It runs the same server pipeline as the site: you register an upload, send the bytes, start a conversion job, then download the result — all authenticated with an API key.

Create an API key in your account

Authentication

Every request carries your key in the Authorization header (Bearer), or an X-API-Key header. Treat it like a password — it spends your account's conversion quota.

https://api.swapfile.ioLive

curl https://api.swapfile.io/v1/jobs/{id} \
    -H "Authorization: Bearer sf_live_..."

Converting a file

heic → jpeg

# 1 · register the upload → presigned URL
curl -X POST https://api.swapfile.io/v1/uploads \
    -H "Authorization: Bearer sf_live_..." \
    -H "Content-Type: application/json" \
    -d '{"size": 48213}'
→ {"file_id":"9f2c…","upload_url":"https://…"}

# 2 · send the raw bytes to that URL
curl -X PUT --upload-file photo.heic "$UPLOAD_URL"

# 3 · start the conversion
curl -X POST https://api.swapfile.io/v1/jobs \
    -H "Authorization: Bearer sf_live_..." \
    -H "Content-Type: application/json" \
    -d '{"file_id":"9f2c…","operation":"convert:jpeg","params":{"quality":"82"}}'
→ 202 {"id":"7ab1…","status":"queued"}

# 4 · poll until done, then download
curl https://api.swapfile.io/v1/jobs/7ab1… \
    -H "Authorization: Bearer sf_live_..."
→ {"status":"done","download_url":"https://…"}
