Thumbor 7.0.0 upsizing all JPEG images to MAX_WIDTH/MAX_HEIGHT

Thumbor request URL

unsafe/filters:format(jpeg)/https://raw.githubusercontent.com/thumbor/thumbor/master/docs/images/blur_before.jpg

Expected behaviour

Thumbor 7.0.0 should retain the original image size and convert it to a jpeg.

Actual behaviour

Thumbor is instead upsizing the image up to the MAX_WIDTH or MAX_HEIGHT set when there isn’t a specified target size.

MAX_WIDTH and MAX_HEIGHT are set to 5000 on my server so in the above image example it returns an image of 3326x5000. Only seeing this issue after upgrading to thumbor 7.0.0 with no changes to config. On Thumbor 6.7.5 it retains the original source image’s dimensions

When MAX_WIDTH and MAX_HEIGHT are not set at all Thumbor 7.0.0 will retain the source image’s dimensions properly

Operating system

Debian 11

Your thumbor.conf

Only included settings changed from default:

MAX_WIDTH = 5000
MAX_HEIGHT = 5000
AUTO_WEBP = True
MAX_AGE = 315360000
ENGINE_THREADPOOL_SIZE = 2
STORAGE = 'thumbor.storages.no_storage'

# Tried with optimizer on and off and made no difference
OPTIMIZERS = [
    'thumbor.optimizers.jpegtran'
]

USE_CUSTOM_ERROR_HANDLING = True
ERROR_HANDLER_MODULE = 'thumbor.error_handlers.sentry'
SENTRY_DSN_URL = redacted
