JPG Usein kysytyt kysymykset konversioista
What is a JPG file?
+
JPG is a lossy raster image format. The encoder discards visual information the human eye is less sensitive to in exchange for dramatically smaller file sizes than equivalent lossless formats. Recompressing a JPG repeatedly causes cumulative quality loss, so always edit from a lossless master where possible.
When should I convert JPG to another format?
+
Convert JPG to PNG, WebP or TIFF when you need an image with no further lossy compression — for archival, for editing, or when the target medium (print, banner ad, product photo) demands maximum fidelity.
Will converting JPG reduce image quality?
+
Converting JPG to a lossless format like PNG locks in the current pixels with no further loss. Converting JPG to another lossy format causes generational quality loss because the new encoder re-encodes already-lossy data — keep the source if you plan to edit further.
Does MOV.to keep my JPG files private?
+
Your JPG files are processed over HTTPS, never read by humans, and deleted from our servers automatically after conversion. No watermarks, no email signup, no resale of image data.
How large a JPG file can I convert?
+
Free users can upload JPG files up to 100 MB. Pro users go up to several GB per file and can batch-convert many files in one job.
Can I convert JPG on my phone?
+
Yes. MOV.to runs entirely in the browser, so iPhone, iPad and Android users can convert JPG files without installing any app. The result downloads straight to your camera roll or downloads folder.
Do I need Photoshop or any other software for JPG?
+
No. The conversion runs server-side. You upload JPG, pick the target format, and download the result — no Photoshop, GIMP, ImageMagick or local install required.
Can I batch-convert many JPG files at once?
+
Yes. Upload multiple JPG files in a single drop and MOV.to converts them in parallel. Free users can queue a couple at a time; Pro users have unlimited batch conversion.
Is converting JPG on MOV.to free?
+
Yes — single-file JPG conversion is free with no signup. Pro features (very large files, batch jobs, OCR, advanced edits) live behind an optional plan.
What output format gives the best result for JPG?
+
For web delivery, convert JPG to WebP — smaller files, similar quality. For editable masters, use PNG or TIFF. For email and broad compatibility, JPG remains the safe default.
