How do I convert JPG to PSD without losing image quality?
+
Upload your JPG file, then our converter applies format-aware quality optimization for PSD output. For lossless formats (PNG, TIFF, BMP) we preserve every pixel; for lossy formats (JPG, WebP) you can tune the quality factor before download.
Transparency survives when going to PNG, WebP, TIFF, GIF or SVG. Converting to JPG flattens the alpha channel against a white background — if you need transparency, target a transparency-aware format instead of PSD.
Embedded ICC color profiles are read from the source JPG and re-attached to the PSD output where the format supports it (JPG, PNG, TIFF, WebP). Formats without profile support fall back to sRGB.
Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during JPG → PSD conversion when both formats support metadata. Use the privacy option to strip metadata before download if you want to share images without geolocation.
Yes — drag multiple JPG files into the upload zone and we queue them in parallel. Free users get 100MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
For straightforward format conversion we run the same libpng / libjpeg-turbo / libwebp / ImageMagick pipelines a desktop editor uses, with the same quality. The difference is that desktop tools open one file at a time; we accept a batch and run them in parallel.
Default behaviour is 1:1 — your PSD output has the same pixel dimensions as the source JPG. If you need to resize as part of the conversion, use the /resize-image/ tool after conversion, or chain it with the /image-resize/ utility.
For JPG / WebP, quality 75-85 typically gets the file 60-80% smaller than the source JPG with no visible difference at normal viewing distance. For lossless targets (PNG, TIFF), expect smaller savings — usually 5-30% via better deflate / LZW compression.
Yes — uploaded JPG files are processed in isolated workers and deleted within minutes. We never read, store, or share the pixel data. The full privacy policy and retention window are documented at /privacy/.
Yes for free up to 100MB. Premium handles larger inputs (300MB+) and exotic per-pixel depths (16-bit PNG, 32-bit float TIFF). The pipeline streams pixel rows, so memory use scales with the row count not the total pixel count.
A JPG file with strong compression (e.g. heavily lossy JPG) often grows when re-encoded to a lossless PSD (PNG, TIFF), and a high-bitrate lossless JPG often shrinks dramatically when going to JPG/WebP. The ratio depends on image content (photos compress differently from line art).
Yes. The conversion is a format change — copyright on the image content stays with you (or whoever held it on the source JPG). We add no watermark, no metadata stamp, and claim no licence over the output.

JPG

JPG 文件采用针对照片优化的有损压缩,在保持视觉质量的同时,提供较小的文件大小。

PSD

PSD(Photoshop 文档)是 Adobe Photoshop 的原生文件格式。PSD 文件存储分层图像,支持无损编辑并保留设计元素。它们对于专业图形设计和图像处理至关重要。
