Uploading images
6 questions about uploading images.
Uploading images
What file formats can I upload?
JPEG, PNG, WebP, and HEIC. Files are automatically converted to WebP for fast gallery loading. Originals are preserved in storage.
Is there a file size limit?
Individual files can be up to 100 MB. Uploads are split into chunks, so large files upload reliably even on slower connections. If a chunk fails, it retries automatically.
Can I upload entire folders?
Yes. Drag a folder onto the upload zone and all supported images inside it are queued. Folder structure is not preserved — images are added flat to the gallery.
How does chunked upload work?
Each file is split into smaller pieces and uploaded in parallel. If your connection drops, only the failed chunk is retried — not the entire file. Upload speed adapts automatically to your connection.
What happens after upload?
Images enter the processing queue. Skerp generates a display-optimized WebP, a high-resolution preview, responsive thumbnail variants, and a blur-up placeholder. Processing runs in the background — the gallery is usable as soon as thumbnails are ready.
How are images ordered?
Each gallery has a "Sort photos by" setting: filename (the default), date taken, or file date. Date taken uses the camera's capture time and falls back to the file date for photos without one. Your gallery pages, the client gallery and PDF exports all follow the same order. Change it under Appearance in the gallery settings, or set a default in Gallery Defaults.
