An online image compressor can run in your browser or send your picture to a server. Those designs have different privacy implications, even when their upload buttons look similar. Before selecting a tool, ask where the image goes, what the site stores, and what information will remain in the file you share. No short slogan can answer all of those questions.
Local processing and server processing
A browser-based tool can read a file after you select it, decode it locally and generate a new downloadable file. The image does not need to leave your device for those steps. A server-based tool typically transfers the image elsewhere, processes it there and returns a result. Its operator and service providers may then handle the uploaded data.
Server processing is not automatically improper, and local processing is not a complete security guarantee. The useful distinction is whether the behaviour fits your needs and whether the disclosure matches it. A confidential document may require an approved organisational workflow regardless of a public website's design.
Simpixly's Image Compressor, Image Resizer and Image Converter process supported images in your browser. The application does not upload selected images, generated pixels, filenames or embedded metadata to an image-processing service. It also does not intentionally retain images in browser storage or a cloud account.
A local tool still loads website files
Opening a website requires requests for HTML, JavaScript, styles, fonts and public images. Simpixly may also load its own WebP encoder files when needed; these static-file requests do not contain your selected image. The hosting and security providers can receive access information such as an IP address, request time and requested URL. That is separate from uploading the selected picture, but it is still a privacy consideration.
Read the site's privacy policy for its actual hosting, security and other enabled services. Do not infer that a page has no network activity because it says “no image uploads.” Simpixly's application does not currently enable advertising, analytics or non-essential application cookies. Production platform settings still require verification before public launch.
Check the image itself
Images may contain embedded information that is not visible in a normal preview. Depending on the source, this can include camera details, capture time, location coordinates, thumbnails or editing information. A file can also expose personal information directly through faces, documents, addresses or reflections in the visible picture.
Simpixly re-encodes images without copying the original EXIF, GPS, IPTC or XMP fields into the export. The browser may create technical encoding information such as resolution or colour data. Re-encoding does not redact visible text or hide a person's face, and it should not be treated as a complete anonymisation tool.
For sensitive sharing, inspect the exported file with an appropriate metadata viewer and look carefully at the pixels. Keep the original separate from the shareable version. Our format guide also explains changes that can occur when an image is re-encoded.
What you can observe yourself
A technical user can inspect the browser's Network panel. Load the tool and its required files, clear the network log, then select, process, download and clear a test image. Investigate any request carrying image bytes, filenames, dimensions or task parameters. Avoid using a sensitive real image for this experiment.
Disconnecting after the necessary tool and encoder files have loaded offers another useful check: local processing should continue for an already loaded tool. It is only one observation, not proof of every future behaviour or every platform configuration. Opening a new page offline may fail because the browser has not loaded its files. Simpixly does not promise a fully offline website or install an offline cache.
Make a decision for the particular task
Use a current browser, keep your device protected, and check that you are on the intended website. Read the relevant privacy disclosure before processing work documents or regulated information. Avoid tools that make promises without explaining image handling, retention and access data.
After processing, open the downloaded image to confirm that it is valid and suitable. Clear the tool when finished. Image references are released when you clear or leave it, subject to the browser's memory and download handling; downloaded files remain wherever you save them.
If you need to report a problem, describe the browser, file format, approximate dimensions and error message without sending the original image. Use the confirmed channel on the Contact page. The Privacy Policy explains the application's current behaviour and identifies disclosures that require the site owner's review before public launch.
