Hello, I would like to know of any effective method that can help me compress the images that are uploaded to the site in a binary field and that they are saved compressed in my database.

Hi,

Python's 'PIL'(pillow) library can be used to compress images. You can use the following custom method:

from PIL import Image

from io import BytesIO

import base64


def compress_image(image_base64, quality=70):

    # Decode the base64 image

    image_data = base64.b64decode(image_base64)

    # Open image with PIL

    image = Image.open(BytesIO(image_data))

    # Convert to RGB if needed

    if image.mode in ("RGBA", "P"):

        image = image.convert("RGB")

    # Compress the image

    output_io = BytesIO()

    image.save(output_io, format="JPEG", quality=quality)

    # Encode back to base64

    compressed_image_base64 = base64.b64encode(output_io.getvalue()).decode('utf-8')

    return compressed_image_base64


And modify your model’s write and create methods to automatically compress images on save>

from odoo import models, fields, api


class MyModel(models.Model):

_name = 'my.model'


image = fields.Binary("Image")


@api.model

def create(self, vals):

if vals.get('image'):

vals['image'] = compress_image(vals['image'])

return super(MyModel, self).create(vals)


def write(self, vals):

if vals.get('image'):

vals['image'] = compress_image(vals['image'])

return super(MyModel, self).write(vals)


Hope it helps
