Best Free Squoosh Alternatives in 2025
Bulk compress, convert, and edit images in your browser — more formats, more tools, same privacy-first approach as Squoosh.
Squoosh (built by Google Chrome Labs) is an excellent browser-based image compression tool — but it's designed for compressing one image at a time with side-by-side codec comparison. If you need bulk processing, format conversion, PDF tools, or a broader set of image editing features while keeping the same privacy-first, no-upload approach, PicsSizer covers all of that.

Why Switch from Squoosh to PicsSizer?
Batch / bulk processing
Squoosh compresses one image at a time — you must reload and re-upload for every file. PicsSizer's Bulk Image Compressor handles up to 100 images simultaneously with a single quality setting, downloading all results as one ZIP file.
Same privacy model, more features
Like Squoosh, PicsSizer processes images entirely in your browser with no server uploads. But PicsSizer extends this to a full toolkit: resizing, cropping, PDF tools, AI background removal, and more — all with the same local-processing privacy.
Actively maintained
Squoosh has not received significant updates since 2023 and may eventually be discontinued. PicsSizer is actively developed with regular feature releases and format support updates.
Target file size mode
Squoosh compresses by quality level — you specify a quality (0–100) and see the resulting size. PicsSizer's target-size mode works in reverse: you specify the desired file size (e.g., 100KB) and the tool automatically finds the right quality level.
PDF and document tools
PicsSizer includes Image to PDF, Merge PDF, Split PDF, and Rotate PDF — all browser-based. Squoosh has no PDF features.
More editing tools
PicsSizer adds rotate, flip, crop, watermark, blur, pixelate, redact, favicon generator, and app icon generator tools that Squoosh doesn't have. If you need an image toolkit rather than just a compressor, PicsSizer covers far more ground.

Frequently Asked Questions
Is PicsSizer better than Squoosh?
For different use cases. Squoosh has more advanced codec controls (MozJPEG, OxiPNG, AVIF options) and an excellent side-by-side comparison mode — ideal for technical image optimization research. PicsSizer is better for batch processing, a broader tool ecosystem (PDF, watermark, resize, background removal), and users who need more than single-image compression.
Does PicsSizer upload images to a server like some alternatives?
No. PicsSizer is fully browser-based — no image data leaves your device. This matches Squoosh's privacy model, which also processes images locally.
Can PicsSizer compress multiple images at once like Squoosh can't?
Yes. Squoosh compresses one image at a time. PicsSizer's Bulk Image Compressor processes up to 100 images simultaneously and downloads them all as a single ZIP file.
Is Squoosh still maintained?
As of 2025, Squoosh hasn't received significant updates since 2023. It still works, but active development appears to have stopped. PicsSizer is actively maintained with regular updates.
Does PicsSizer support AVIF like Squoosh?
Yes. PicsSizer converts to and from AVIF format. Compression quality control for AVIF is available via the Image Converter. Squoosh's AVIF codec options (e.g., cq-level, subsample) are more granular for technical optimization work.
